This monoclonal antibody has been tested for use in western blotting, immunoprecipitation and immunofluorescence. Specific conditions for reactivity should be optimized by the end user. Expect bands approximately 115 and 105 in size corresponding to isoforms of HEF1 protein by western blotting in the appropriate cell lysate or extract. This antibody does not recognize p130Cas. Sin1 has not been tested. IF was performed using 4% PFA fixed cells. This monoclonal antibody mostly detects HEF1 localized at the focal adhesion sites.
