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 inactivated by heat. It is inactivated by heating the food product at a temperature of 240 F (116 C) for 10 minutes. After this time, the enzyme activity is reduced by 95%. …

WebAbstract In order to clarify whether HIV-1 core and env antigens are destroyed during pepsin treatment, used previously for detecting HIV-1 core and env antibodies hidden in circulating immune complexes, purified recombinant env and core antigen preparations were treated with pepsin. Core antigen was found to be extremely sensitive to this enzyme.
WebPepsin is widely used to produce F(ab')2 fragments of immunoglobulin G (IgG). In many cases, at least part of the pepsin will remain present in the F(ab')2 preparation, albeit in (irreversibly) inactivated form. Here we report on a potent immunomodulatory effect of irreversibly inactivated pepsin on activated human neutrophils.
