Background Information
Pepsinogen I belongs to the peptidase A1 family. It shows particularly broad specificity and although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent. The gene encodes a 388 amino acid protein with a 15 amino acid signal peptide and 46 amino acid propeptide. This antibody can recognize PGA3(pepsinogen 3), PGA4(pepsinogen 4), PGA5(pepsinogen 5).
