Immobilized Papain

Papain is a cysteine protease enzyme (EC 3.4.22.2) that has the endopeptidase activity to cleave

immunoglobulin G molecules in the hinge region.  This cleavage results in the generation of three ~50kDa

fragments; two Fab domains and a Fc domain.  The papain-digested antibody is unable to promote

agglutination, precipitation, opsonization, and lysis. The Fab and Fc fragments can be further separated with

either Immobilized Protein A or ion exchange chromatography. Immobilized Papain is a convenient

reagent for producing Fab and Fc fragments as it avoids the need to remove the papain enzyme after

digestion.

Features

• Generate Fc and Fabfrom IgG

• Eliminates contamination with papain enzyme

• Can be used in virtually all scenarios using free papain
