Peptide mapping cleaves the protein with trypsin and compares the fragment pattern with the reference; a single substitution or modification shifts a peak. Reversed-phase chromatography quantifies oxidised, deamidated, clipped and extended forms against the main peak. Size exclusion quantifies aggregates. Charge-based methods quantify deamidation directly. No single method covers all of these.
Intact mass, now common, supplements rather than replaces the map.
Host-cell protein by immunoassay and residual DNA by amplification or dye, because the protein was made in cells. Endotoxin by the limulus assay. Sterility for the finished product. These lines distinguish a recombinant protein certificate from a synthetic peptide certificate.
Water content and the content of excipients complete the list for a lyophilised product.
Historically the body-weight-gain assay in hypophysectomised rats; now generally a cell-based proliferation assay against the international standard. It confirms the protein is folded and active, which the chemical tests imply but do not prove. A research-grade certificate reports which of these tests were performed on the lot.
