Cancer and Tumour Marker Antigen products
BBI offers an extensive range of human tumour marker antigen products derived either from native human sources or using carefully chosen recombinant expression systems. All source materials are screened for safety using the latest sensitive methods. Products are made to order or available from stock using processes defined by specific batch records. We endeavour to always supply material to our customers’ timelines but rely on our clients to provide forecasts and estimates of usage.
Materials are prepared using a range of purification technologies, some of these unique to BBI. Products are available as either highly purified or part-purified grades, are formulated to optimise shelf-life and provide material in the most convenient storage format. Analytical testing is performed to demonstrate the product purity and recovery using immunological and/or biochemical protein assays.
