Production and characterisation of monoclonal and polyclonal amtobpdoes agaomst bovine osteocalcin.
Monoclonal and polyclonal antibodies were produced against osteocalcin purified from bovine bone. The antibodies were used for the development of a two-site ELISA. A monoclonal antibody recognising residues 15-49 of bovine osteocatcin generated by cleavage with 70% formic acid was used as capture antibody and a biotinylated polyclonal antibody recognising the same peptide was used for detection. The two-site assay did not detect any tryptic peptides of bovine osteocalcin (residues 1-19, 20-43, and 45-49) nor did it detect the peptide 1-14 or the synthetic peptide 37-49. Cross-reaction was observed for osteocalcin in plasma from sheep, goat, chicken and human but not for osteocalcin from rat and pig.
