These CD317 ELISA kits are immunodetection tools for measuring the levels of CD317 in biological samples. CD317 is an alias of the human BST2 gene, which encodes the protein, bone marrow stromal cell antigen 2. Notably, CD317 is known to play a role in innate immune responses, among other functions. The BST2 protein is described to be 180 amino acid residues in length and 19.8 kilodaltons in mass. It is localized to the cell membrane, golgi, and cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in the liver, lung, heart and placenta. This protein is known to be ubiquitinated and glycosylated. Other names for this target antigen include HM1.24. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
