These HERP ELISA kits are immunodetection tools for measuring the levels of HERP in biological samples. HERP is an alias of the human HERPUD1 gene, which encodes the protein, homocysteine inducible ER protein with ubiquitin like domain 1. Notably, HERP is known to play a role in the regulation of apoptosis, among other functions. The HERPUD1 protein is 391 amino acid residues in length and 43.7 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the ER of the cell. In terms of tissue specificity, it is reported to be widely expressed in the brain, expression seems to be restricted to neurons and vascular smooth muscle cells. Other names for this target antigen include Mif1. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
