Vaccine and Cell technology service company
JAS Biological

Protein purification, assays, downstream processing, conjugation and molecular biology.

Our senior scientists have a proven track record in the development of innovative assay methodologies. This has resulted in patented proprietary technologies and publications in peer-reviewed scientific journals. As a client you will benefit from two decades of experience in process development and the provision of innovative solutions for assay design. We have the experience and capability to produce and process biological material in milligram to multi-gram quantities. With facilities for both mammalian and microbial cell culture we can process whole cells, cell fragments, cellular extracts or secreted products using your existing protocols; or by developing new, validated procedures. Our expertise extends from routine immunoglobulin purification to process development and downstream processing for novel recombinant protein production.
