Anti-HSP70-1A antibodies are used in antigen-specific immunodetection in biological samples. The target HSP70-1A is a known alias name of the protein heat shock protein family A (Hsp70) member 1A, encoded by the HSPA1A gene in humans. This 641-amino acid residue 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. It is localized to the nucleus, cytoplasm, and is secreted of the cell and features acetylated post-translational modifications. It is reported to be widely expressed in many tissue types. Other synonyms for HSP70-1A include HEL-S-103, HSP70, and HSP70-1. Over 330 citations in the literature describe the use of HSP70-1A antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunoprecipitation, and Immunohistochemistry are also common applications.
