Anti-rabbit IgG for IP (HRP) is a conformation-specific secondary antibody that reacts only with native IgG and does not bind to the denatured and reduced rabbit IgG heavy chain or light chain. When performing immunoprecipitation (IP) followed by western blotting, the denatured rabbit IgG light (25 kDa) and heavy (55 kDa) chains of the primary antibody used for IP will not be recognized by Anti-rabbit IgG for IP (HRP), improving the specificity of protein detection.
