Bio-Rad: Recombinant fully human isotype controls

Use fully-human recombinant monoclonal antibodies as negative controls in antibody drug discovery and development, and in vitro diagnostic assays. Negative controls differentiate the non-specific background signals initiated by the antibody Fc domain or other cellular protein interactions, from the target-specific antibody signal. Bio-Rad’s recombinant antibodies are expressed in a mammalian cell line, ensuring continuity of supply and consistent quality from batch to batch, and overcome the challenges of sourcing control immunoglobulins from human sera.
