Conjugated Primary Antibodies

Most protein and cell analysis techniques involving antibodies depend upon using target-specific primary antibodies and labeled, conjugated secondary antibodies. However, using directly labeled primary antibodies enhances or simplifies certain procedures. For example, commercially available ELISA kits typically use matched pairs of target-specific (primary) antibodies in which the detector antibody of the pair is biotinylated. This arrangement enables sensitive and reliable signal generation, and amplification occurs by probing the biotin label with HRP-conjugated streptavidin. We offer many primary antibodies conjugated to different fluorescent and enzymatic labels including Alexa Fluor, HRP, and AP.
