Isotype controls are primary antibodies that lack specificity to the target, but match the class and type of the primary antibody used in the application. Isotype controls are used as negative controls to help differentiate non-specific background signal from specific antibody signal.

Our Rabbit IgG Isotype Control-ATTO Fluor-647N (#RIC-001-FRN), was specifically developed to be used as a negative control in immunohistochemistry and surface staining flow cytometry applications, along our line of rabbit primary antibodies conjugated to the ATTO Fluor-647N fluorophore.
