The ability of the MAbs to recognize full length human osteocalcin, tryptic 1-19, 20-43, synthetic 7-19, 15-31 and bovine osteocalcin was tested with Eu-labelled antigens. See the printable version for further information. MAbs are working in ELISA. Recommended pairs are (coating - conjugate): 3G8 - 2H9 (specific for the intact hOC) 2H9 - 6F9 (detects also the large NH2- terminal fragment)
