Anti-HSP70I antibodies are protein reagents that detect specific antigens. The HSP70I antigen is another term for the human protein heat shock protein family A (Hsp70) member 1A, encoded by the HSPA1A gene. The protein is known to be a molecular chaperone implicated in a wide variety of cellular processes, including protection of the proteome from stress, folding and transport of newly synthesized polypeptides, activation of proteolysis of misfolded proteins and the formation and dissociation of protein complexes. Canonically, it has an amino acid length of 641 residues and a mass of 70.1 kilodaltons. Its subcellular localization is in the nucleus, cytoplasm, and is secreted. It is widely expressed in many tissue types. The HSP70I protein is a member of the Heat shock protein 70 protein family. Other alias names for HSP70I include HEL-S-103, HSP70, and HSP70-1. Over 330 citations in the literature describe the use of HSP70I antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunoprecipitation, and Immunohistochemistry are also common applications.
