These CD123 ELISA kits are immunodetection tools for measuring the levels of CD123 in biological samples. CD123 is an alias of the human IL3RA gene, which encodes the protein, interleukin 3 receptor subunit alpha. Notably, CD123 is known to play a role in cytokine-mediated signaling pathways, among other functions. The IL3RA protein is 378 amino acid residues in length and 43.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include IL-3R-alpha. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
