Product Overview
This rabbit polyclonal antibody recognizes heat shock 70 kDa protein 1-like (gene HSPA1L) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 70.4 kDa, and the supplier reports an observed band at about 70 kDa.
HSPA1L (HSP70-1-like, also called HSP70-hom) is an HSP70-family chaperone encoded next to HSPA1A and HSPA1B in the MHC region. It is expressed at higher levels in testis and is not strongly heat-inducible, and like other HSP70s it helps fold and protect proteins.
