Anti-HSP32 antibodies are used in antigen-specific immunodetection in biological samples. The target HSP32 is a known alias name of the protein heme oxygenase 1, encoded by the HMOX1 gene in humans. This 288-amino acid residue protein is known to be involved in angiogenesis and the cellular response to hypoxia, among other biological processes. It is localized to the ER of the cell. In terms of tissue expression, it is noted to be expressed at higher levels in renal cancer tissue than in normal tissue. Other synonyms for HSP32 include HMOX1D and HO-1. Over 200 citations in the literature describe the use of HSP32 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunohistochemistry are also common applications.
