Anti-CD200RLa antibodies are used in antigen-specific immunodetection in biological samples. The target CD200RLa is a known alias name of the protein CD200 receptor 1 like, encoded by the CD200R1L gene in humans. This 271-amino acid residue protein is believed to be a receptor for the CD200/OX2 cell surface glycoprotein. It is localized to the membrane of the cell and features glycosylated post-translational modifications.
