Inactivated pepsin fragment
WebPepsin and papain are often used to generate antibody fragments. Papain is used to cleave antibodies into Fab fragments, which contain a single antigen-binding domain. Pepsin is used to generate F (ab')2 fragments by removing only that portion of the Fc domain beyond the hinge region. WebPepsin is a nonspecific acidic endopeptidase produced in an inactive precursor form (pepsinogen) in the mucosal lining of the stomach of vertebrates. There are several …
