These PRSS24 ELISA kits are immunodetection tools for measuring the levels of PRSS24 in biological samples. PRSS24 is an alias name of the human STEAP1 gene, which encodes the protein, STEAP family member 1. The protein is a reported metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+). The STEAP1 protein is described to be 339 amino acid residues in length and 39.9 kilodaltons in mass. It is localized to the endosome of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. Other names for this target antigen include STEAP.
