Rat IgG isotype controls include monoclonal antibodies that target E. coli β-galactosidase (β-Gal) and a control serum for polyclonal rat IgG. These negative control antibodies are designed for use with the corresponding primary antibodies of the same isotype. Choosing the appropriate negative control is critical for confirming the specificity of primary antibody binding and for ruling out non-specific Fc receptor binding.
