Anti-POC1B-GALNT4 antibodies are used in the immunodetection of the protein POC1B-GALNT4 readthrough. Synonyms for this target antigen include POC1B-GALNT4 fusion, Polypeptide GalNAc transferase 4, Protein-UDP acetylgalactosaminyltransferase 4, UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 4, pp-GaNTase 4, and POC1B-GALNT4 protein. These POC1B-GALNT4 antibodies are widely used in Western Blot experiments, among other applications.
