Bioprocessing buffers and reagents   

We offer an extensive array of downstream processing buffers and reagents for protein, cellular, and viral-based therapeutics. Produced in our ISO:13485 plants which are cGMP compliant. 

  

The process begins with approved and specified raw materials obtained from qualified vendors. Our instances on superior-quality materials include complete NAO (non-animal origin) traceability and our Water for injection (WFI) systems meet both US and European Pharmacopoeia Standards. Standard testing on finished media products includes tests of sterility, osmolality, pH, and endotoxin content.
