Anti-NPD008 antibodies are used in antigen-specific immunodetection in biological samples. The target NPD008 is a known alias name of the protein trans-golgi network vesicle protein 23 homolog B, encoded by the TVP23B gene in humans. This 205-amino acid residue protein is known to be involved in vesicle-mediated transport, among other biological processes. It is localized to the membrane of the cell. Other synonyms for NPD008 include CGI-148, FAM18B, and FAM18B1.
