These QPD ELISA kits are immunodetection tools for measuring the levels of QPD in biological samples. QPD is an alias of the human PLAU gene, which encodes the protein, plasminogen activator, urokinase. Notably, QPD is known to play a role in chemotaxis and the regulation of cell migration, among other functions. The PLAU protein is 431 amino acid residues in length and 48.5 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be expressed in the prostate gland and prostate cancers. This protein is known to be glycosylated, cleaved and phosphorylated. Other names for this target antigen include ATF and BDPLT5. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
