Anti-RFPL4B antibodies are used in the immunodetection of the protein ret finger protein like 4B. In humans, the canonical protein has a reported length of 263 amino acid residues and a mass of 29.9 kDa. RFPL4B is known to be involved with protein ubiquitination and the regulation of gene expression. Synonyms for this target antigen include RING finger protein 211. RFPL4B gene orthologs have been reported in the mouse, rat and chimpanzee species. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for RFPL4B antibodies.
