Rhodamine Red-X-conjugated AffiniPure Fab Fragment Goat Anti-Alpaca IgG, VHH domain ( min X Bov Sr Prot)

Fab fragment antibodies are generated by papain digestion of whole IgG antibodies to remove the entire Fc portion, including the hinge region. These antibodies are monovalent, containing only a single antigen binding site. The molecular weight of Fab fragments is about 50 kDa. Based on immunoelectrophoresis, Western blot and/or ELISA, the antibody reacts with the VHH domain of heavy chain (HC) alpaca IgG, subclasses 2 and 3; and with the VHH domain of llama IgG, subclasses 2 and 3. It also reacts with whole molecule alpaca and llama IgG1. No antibody was detected against non-immunoglobulin serum proteins. The antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with bovine serum proteins, but it may cross-react with immunoglobulins from other species.
