These Bri ELISA kits are immunodetection tools for measuring the levels of Bri in biological samples. Bri is an alias name of the human ITM2B gene, which encodes the protein, integral membrane protein 2B. Notably, Bri is known to play a role in nervous system development, among other functions. The ITM2B protein is 266 amino acid residues in length and 30.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the golgi and cell membrane of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be glycosylated and cleaved. Other names for this target antigen include ABRI and BRI2.
