Inactivated pepsin fragment
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 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.
