These QIP1 ELISA kits are immunodetection tools for measuring the levels of QIP1 in biological samples. QIP1 is an alias of the human KPNA4 gene, which encodes the protein, karyopherin subunit alpha 4. The protein is reported to function in nuclear protein import as an adapter protein for nuclear receptor KPNB1. The KPNA4 protein is described to be 521 amino acid residues in length and 57.9 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 testis, ovary, small intestine, heart, skeletal muscle, lung and pancreas, but barely detectable in kidney, thymus, colon and peripheral blood leukocytes. Other names for this target antigen include IPOA3 and SRP3. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
