The CD339 ELISA kits listed below are analytical tools for measuring concentrations of CD339 in various samples. CD339 is an alternative name for the human JAG1 gene, which encodes the protein, jagged canonical Notch ligand 1. It has been mentioned that CD339 plays a role in angiogenesis, among other functions. Structurally, the JAG1 protein is 1218 amino acid residues in length and 133.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is found to be widely expressed in adult and fetal tissues. This protein is known to be glycosylated. Other names for this target antigen include AGS, AGS1, and AHD. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
