Anti-RPL19 antibodies are used in the immunodetection of the protein ribosomal protein L19. In humans, the canonical protein has a reported length of 196 amino acid residues and a mass of 23.5 kDa. Its subcellular localization is in the cytoplasm. A member of a the Eukaryotic ribosomal protein eL19 protein family, RPL19 is a known component of the large ribosomal subunit. Synonyms for this target antigen include eL19, 60S ribosomal protein L19, large ribosomal subunit protein eL19, and L19.
