Rabbit Anti-Goat IgG Fab Fragment Polyclonal Antibody-[FITC]

Goat IgG fab fragment is a derived protein from goat serum, known for its role in the adaptive immune response. This fragment consists of the antigen-binding portion of the immunoglobulin G (IgG) molecule, which is crucial for recognizing and binding to specific antigens. The Fab fragment is composed of one complete light chain and the N-terminal domain of a heavy chain, forming the antigen-binding site. It plays a significant role in immune diagnostics, particularly in assays like ELISA and Western blot, where it can be used for detection and quantification of specific antigens. The Goat IgG Fab Fragment is also used in immunoassay procedures, such as a second antibody reagent, for conjugation with enzymes or fluorescent dyes, and in the internalization of 125I-IgG by streptolysin-O-permeabilized cells.
