  • Title: Fragmentation of immunoglobulin G.
    Author: Andrew SM, Titus JA.
    Journal: Curr Protoc Cell Biol; 2003 Feb; Chapter 16():Unit 16.4. PubMed ID: 18228421.
    Abstract:
    For some purposes, fragments of the IgG molecule are preferred. The F(c) portion is useful for studies of biological effect-binding to the F(c) receptor, mediating antibody-dependent cellular cytotoxicity, and complement fixation. The bivalent F(ab')(2) produced by digestion with pepsin and the monovalent Fab produced by digestion with papain are useful for studies based on the interaction between antibody binding site(s) with antigen. This unit also describes alternative methods for preparing F(ab')(2) fragments.
