Anti-CsA-19 antibodies are used in antigen-specific immunodetection in biological samples. The target CsA-19 is a known alias name of the protein ribosomal protein L10a, encoded by the RPL10A gene in humans. This 217-amino acid residue protein is a known component of the large ribosomal subunit. It is localized to the cytoplasm of the cell. It is reported to be widely expressed in many tissue types.
