At TCS Biosciences Ltd, we have gained an outstanding reputation for service and satisfaction through dedication to our first business principle: quality.

Blood from our donor animals continues to play a vital role as a nutritional supplement in microbiological culture media, and also functions as a diagnostic indicator in media and test systems for clinical diagnosis.

Our specialised approach to quality assurance extends from animal husbandry through collection to processing and packaging, to ensure the consistent quality of our products.

Animal blood continues to play a vital nutritional role in microbiological culture media, and also functions as a diagnostic indicator in media and in test systems for clinical diagnosis.

For more than 50 years TCS has specialised in donor animal blood products, and has attained ever-higher standards of quality through continuous improvement of our processes. Quality assurance extends, via our supplier, Preston Farms, from animal husbandry through collection to processing, QC and packaging, to ensure you get the best possible products every time you order.

TCS is currently Europe's leading supplier to the water industry of testing reagents for Cryptosporidium and Giardia. Our range includes the best Fluorescent stains, precise quantitative controls, and our popular Isolate^® IMS equipment and reagents.

Although the stringent water industry Cryptosporidium testing regulations are no longer in force, we have retained our system for ensuring continuity of supply, which means we always have stocks of key products available for immediate despatch.

Isolate^® offers unique, semi automated immunomagnetic separation (IMS) of Cryptosporidium oocysts in environmental water samples. The unique automation of the Isolate^® test standardises the rocking motion, resulting in improved consistency and reliability of results.

Isolate^® yields increased recoveries of oocysts and produces good results even when using dirty water samples. In addition Isolate^® is able to process pellets up to 2 ml in volume, reducing the need for split samples and multiple slides.

Cryptosporidium oocysts in the concentrate are captured and separated by magnetic action. Separated oocysts are stained with an approved Fluorescent antibody stain, and visualised by fluorescence microscopy.

Since we began offering Fluorescent stains in 2000, we have emerged as Europe's leading specialist supplier of Cryptosporidium and Giardia positive controls, reagents and equipment. We have focused on building a product range that includes innovative products from around the world, and which is unrivalled by any other supplier of Cryptosporidium and Giardia related products in Europe.

Bovine Serum Albumin is a large, stable, soluble, monomeric, globular protein which makes up about half of the total serum protein. Due to its binding and transporting properties, BSA acts primarily as a carrier protein for hormones, fatty acids, trace minerals, vitamins and iron. However, it also plays a role in stabilising extracellular fluid volume and maintaining osmotic balance, as well as binding harmful toxins and free radicals.

Its in vitro uses are diverse, ranging from pharmaceutical and medical applications to agriculture and chemical manufacture.

We also offer a batch reservation service. Please enquire for more details.

Also available in larger pack sizes, please contact us for details.
