Purity

One Step Ahead

The use of genetically engineered protein A/G (lacking the albumin binding domain) and cultivation in serum- or protein-free media guarantee highest quality. After one-step purification with affinity chromatography our monoclonal antibodies are of highest purity without detectable traces of bovine IgGs or serum albumins. Remaining aggregates can be quantitatively removed with preparative size-exclusion chromatography. Antibodies to be used in preclinical trials are supplied free of endotoxins with cGMP compliant documentation if required.
