TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 136
To: Customers purchasing Selectrol®
It is our intention to change the source strain of the product listed below. The details of the change and the reason for it are given below..
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Yersinia enterocolitica 1st generation derivative from NCTC® 12982
Product code: MM80
Proposed Change Date: 01.12.2024
Change Details:
Storage conditions for this strain will be changed to -30°C to -15°C from -20°C to +8°C.
Reason for Change:
As part of our on-going shelf-life work we have recently completed a series of shelf life studies for MM80.
The results showed when stored at fridge temperatures (2-8°C) there are insufficient colony forming units to support the stated shelf life.
This strain will therefore be labelled for freezer storage (-30°C to -15°C) only.
Considerations:
All vials of MM80 despatched from 01 December will be labelled as described above.
We recommend that any existing stock of MM80 at customer facilities is transferred to freezer storage if it is currently refrigerated.

Bactiscan™ and BactiscanPRO™
TCS Biosciences are delighted to announce we are the UK distributors for the EIT Bactiscan™ and BactiscanPRO™ range of handheld bacteria and biofilm detection systems
Bactiscan™ products utilise proprietary wave-alternating UV light technology to locate surface contamination, especially as a prelude to ATP swab testing in production facilities. Being lightweight, and easy-to-use, one operator can examine large areas quickly, with minimal training required. The products are environmentally friendly and safe for people and products, as it requires no chemicals to generate results. BactiscanPRO™ utilises still photography and video capture capability for maintenance and remedial works.
Bactiscope™ also uses the same wave-alternating UV light technology, but is designed to inspect awkward to access areas and inside pipework. Images or video captured can be uploaded to an internal quality system for audit purposes or documented corrective action.
Extremely environmentally friendly as it requires no chemicals or dyes.
- Immediately isolate areas of bacteria, biofilms, mould, product residue and many other contaminants
- Inspect large surface areas quickly and easily
- Environmentally friendly, non-invasive, and safe to handle / use
- For most areas, downtime is not required
- Can help save money by making other testing, such as ATP swab tests, more targeted and efficient

We would like to apologise to our customers who viewed and/or printed Certificates of Analysis for our Selectrol® products between 24 January and 1 March 2023.

If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Horse and Sheep Blood products as listed
Proposed Change Date: 01 January 2023
Change Details:
The products listed in Appendix 1 will no longer be available in our catalogue.
Reason for Change:
We have been reviewing sales of our Horse and Sheep blood products. There are insufficient sales of the products listed in Appendix 1 to continue to include them in our catalogue from 2023.
Considerations:

TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 109
To: Customers purchasing Bacticount Dipslides
It is our intention to change the Manufacturing Process of the products listed below. The details of the change and the reason for it are given below.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Bacticount Dipslides
Proposed Change Date: Dipslides manufactured June 2022 onwards
Change Details:
Bacticount Dipslides will no longer include a cap.
Reason for Change:
We have been informed by Dimanco, the manufacturer of dipslides, that the plastic caps will no longer be included with Bacticount Dipslides.
The rising costs of plastics raw materials and consideration of the environmental benefits, including reduction of carbon footprint, to not including caps with these products are the key reasons for this change.
Considerations:
There is no change to the standard 6 month shelf life of the products; however extended shelf life to 9 months will no longer be possible.
Conclusion
There is no effect on the quality of the products. The caps have been an aesthetic addition to the slides.

TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 104
To: Customers purchasing Stain HD products
It is our intention to change the IVD status of the products listed below. The details of the change and the reason for it are given below.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: StainHD products as specified below
Product codes: Product codes prefixed HS and HDS. HC6405 Periodic acid (1% aqueous)
Proposed Change Date: 26 May 2022
Change Details:
Products with codes as listed above will no longer be CE marked but will carry the UKCA mark.
From this date StainHD products will be available for UK sale, but no longer available for sale in the EU.
Reason for Change:
The products listed in this change control are currently CE marked in accordance with the IVD Directive.
These products will carry the UKCA mark in accordance with the UK Medical Devices Regulations 2002 (SI 2002 No. 618) as amended, for in-vitro diagnostic medical devices from 26 May.
The CE mark will be removed from these products from 26 May.
Considerations:
From 26 May 2022 Regulation 2017/746 the EU IVDR will come into force in the EU. This regulation will not apply to the UK. TCS Biosciences has taken the commercial decision not to transition the StainHD product range to IVDR, therefore the CE mark will be removed from these products and they will not be available for sale in the EU.
From 26 May 2022 IVD registration of the StainHD products with product codes listed above in Great Britain will be in accordance with the UK Medical Devices Regulations 2002 and thus the product labels will carry the UKCA mark.
Conclusion
The changes listed above have no effect on the formulation and quality of the StainHD products included in this change control.

TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 98
To: Customers purchasing Stain HD products
It is our intention to change the Manufacturing Process of the products listed below. The details of the change and the reason for it are given below.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Stain HD Dyes and Stains
Product codes: HD codes, HS codes, HDS codes, HK codes
Proposed Change Date: 12 April 2022
Change Details:
An alternative bottle has been approved and may be used to supply 500ml and 1L volumes to customers.
Reason for Change:
Due to the current extraordinary circumstances of Covid-19 pandemic, world-wide shortage of plastics products and their constituent polymers, escalating oil prices and conflict in Ukraine we are currently unable to obtain HDPE bottles from our US supplier for use with 500ml and 1L volumes of products.
Instead, we will be supplying 500ml and 1L volumes of products in HDPE bottles from a UK supplier.
Considerations:
The UK supplier of bottles for both volumes is already an approved supplier with TCS Biosciences.
Although the bottles are different shapes, there is no difference between the two bottle types in terms of plastic used, both are manufactured using HDPE.
Our internal leak testing included filling bottles with aqueous and solvent-based stains, then storing the bottles inverted for at least 2 weeks. At the end of the test there was no evidence of leakage from any of the bottles.
Conclusion
We reserve the right to package our 500ml and 1L volume Stain HD products in HDPE bottles from either of two approved suppliers to ensure we can continue to provide these products to our customers.

TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 95
To: Customers and Distributors of animal blood and serum products
It is our intention to change the status of the products listed below. The details of the change and the reason for it are given below.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Animal Blood and Serum products – see Appendix 1 for full list of products and product codes
Proposed Change Date: 26 May 2022
Change Details:
These products will no longer be classed as in vitro diagnostic products (IVDs). The labels for these products will not include the CE or IVD symbols.
Reason for Change:
Currently the products listed in Appendix 1 are classified as IVDs in accordance with Annex Ill of Directive 98/79/EC and a self-declaration of conformity is available for each product.
Directive 98/79/EC is to be replaced by Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR) for which the date of application is 26 May 2022.
It is a requirement of the IVDR to reclassify all IVDs in accordance with the classification rules. None of the seven classification rules applies to the animal blood and serum products listed in Appendix 1.
As the animal blood and serum products are used as raw materials in manufacture and not as finished products for in vitro diagnosis of patients it will also not be possible to meet all the IVDR requirements for conformity assessment and performance evaluation.
For these reasons the products in Appendix 1 will no longer be classed as IVDs.
Considerations:
The removal of the CE and IVD symbols will have no impact on the manufacturing processes or quality of the products listed in Appendix 1; the change described is solely the removal of IVD status.
These products will continue to be suitable as raw materials for manufacture of IVDs.
TCS Biosciences will retain and maintain the ISO 9001:2015 quality management system, ISO 14001:2015 environmental management system and ISIA (International Serum Industry Association) Traceability Certification in accordance with current practices.
There is no impact on the issue of certificates of analysis for the products listed in Appendix 1.

TCS BIOSCIENCES LTD, CHANGE NOTICE: CCI 93
To: Customers purchasing Stain HD products
It is our intention to change the Manufacturing Process of the products listed below. The details of the change and the reason for it are given below.
Please acknowledge receipt of this notification and confirm your acceptance of the change by completing the section below and emailing a copy of the form to qc@tcsgroup.co.uk. Acceptance of the change is assumed if a response is not received within two weeks of issue of this notification.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: Stain HD Dyes and Stains.
Product code: HD codes, HS codes, HDS codes, HK codes.
Proposed Change Date: 01 March 2022
Change Details:
Stain HD products may be provided in bottles of a larger size than usual.
Reason for Change:
Due to the Covid-19 pandemic the world-wide stocks of plastic products and the polymers used to produce these (including silica) are severely limited. Many bottle types used at TCS Biosciences are now on back[1]order with our suppliers and we anticipate our stocks of some bottles will run out before we receive our orders.
Considerations:
Any larger bottles used to package Stain HD products will be made of the same material as the bottle that is usually used. The volume of product contained within the bottle will be clearly indicated on the label.
Conclusion:
We reserve the right to package our Stain HD products in bottles normally used for larger volumes to ensure we can continue to provide these products to our customers. This is a temporary action and we will revert to using the usual bottles for Stain HD products as soon as we receive stocks from our suppliers.

To: Customers and Distributors of StainHD product range
It is our intention to change the Manufacturing Process of the products listed below. The details of the change and the reason for it are given below.
If you have any difficulties or concerns accepting the change, please contact us immediately.
Product: StainHD product range (see list overleaf)
Proposed Change Date: From 1 March 2022
Change Details:
We are discontinuing some of the products and/or pack sizes from our current catalogue of StainHD products.
Reason for Change:
Due to the on-going Covid-19 pandemic TCS Biosciences continues to focus our production activities on our core products.
We have further reviewed our range of StainHD products and identified those products and pack sizes that are slower selling.
Some products will be discontinued from the range and some other products will have fewer pack sizes available than currently. See list below

This change control is issued to give customers and distributors as much advance notice as possible prior to implementation of the change.
Until 1 March 2022 the products/pack sizes will continue to be available for sale while stocks last.
