Anti-Cv2 antibodies enable researchers to detect and measure the Cv2 antigen in biological samples. This target is a reported synonym of the BMPER gene, which encodes BMP binding endothelial regulator. This protein is known to function in blood vessel development and ear development, among other biological roles. The human version of Cv2 has a canonical amino acid length of 685 residues and a protein mass of 76 kilodaltons. It is reported to be a secreted protein.
