These pirin (iron-binding nuclear protein) ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. pirin (iron-binding nuclear protein) is an alias of the human PIR gene, which encodes the protein, pirin. Notably, pirin (iron-binding nuclear protein) is known to play a role in monocyte differentiation and transcription by RNA polymerase II, among other functions. The PIR protein is described to be 290 amino acid residues in length and 32.1 kilodaltons in mass. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in a subset of melanomas. Other names for this target antigen include pirin (iron-binding nuclear protein).
