Santa Cruz Biotechnology is expanding our monoclonal antibody product line. We offer monoclonal antibodies directed against kinases and phosphatases, representing essentially all targets covered by polyclonal antibodies. The phosphorylation state of a molecule may affect its enzymatic activity, localization, interaction and structure. Each of these potential effects may have a profound impact on cell activity and viability. Kinases phosphorylate specific substrates, while phosphatases remove phosphate groups, together controlling target molecule activity.
