The HSP32 ELISA kits listed below are analytical tools for measuring concentrations of HSP32 in various samples. HSP32 is an alternative name for the human HMOX1 gene, which encodes the protein, heme oxygenase 1. It has been mentioned that HSP32 plays a role in angiogenesis and the cellular response to hypoxia, among other functions. Structurally, the HMOX1 protein is described to be 288 amino acid residues in length and 32.8 kilodaltons in mass. It is localized to the ER of the cell. In terms of tissue specificity, it is noted to be expressed at higher levels in renal cancer tissue than in normal tissue. Other names for this target antigen include HMOX1D and HO-1.
