This Protein G purified antibody has been tested for use in western blotting, immunoelectron microscopy, immunohistochemistry and immunoprecipitation. Specific conditions for reactivity should be optimized by the end user. Expect a doublet band approximately 72/73 kDa in size corresponding to Hsc70 (Hsp73) by western blotting in the appropriate cell lysate or extract. In general, a 1:1,000 dilution is suggested for most applications and is suitable to detect Hsc70 (Hsp73) in 20 µg of heat shocked HeLa cell lysate by western blotting.
