These CD309 ELISA kits are immunodetection tools for measuring the levels of CD309 in biological samples. CD309 is an alias of the human KDR gene, which encodes the protein, kinase insert domain receptor. Notably, CD309 is known to play a role in angiogenesis and cell migration, among other functions. The KDR protein is 1356 amino acid residues in length and 151.5 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cytoplasmic vesicles, ER, and cell membrane of the cell. In terms of tissue specificity, it is notably expressed in cornea. This protein is known to be N-glycosylated, ubiquitinated and phosphorylated. Other names for this target antigen include FLK1.
