Used to produce Fab fragments of antibodies, cell dissociation, morphological isolation of intact cortical neurons from postnatal rats. Limited papaindigestion is used for structural studies of enzymes and other proteins. In addition, papain is used in red cell serology to modify red cell surface to enhance or destroy reactivity of many red cell antigens. Useful for platelet serology studies and has also been used in enzymatic synthesis of amino acids, peptides, and other molecules.
