These Williams-Beuren syndrome chromosome region 28 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Williams-Beuren syndrome chromosome region 28 is an alias of the human TMEM270 gene, which encodes the protein, transmembrane protein 270. The TMEM270 protein is 265 amino acid residues in length and 29.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane of the cell. Other names for this target antigen include Williams-Beuren syndrome chromosome region 28.
