This clone was raised against bovine osteocalcin, and equally recognizes both the bovine and the human osteocalcins. Clone OC4-30 is specific for γ-carboxylated osteocalcin.

This clone was raised against human osteocalcin peptide. It specifically recognizes human osteocalcin with decarboxylated glutamic acid residues, and does not recognize Gla-type osteocalcin.

The Undercarboxylated Osteocalcin (Glu-OC) EIA Kit uses two monoclonal antibodies that are highly specific for undercarboxylated osteocalcin (Glu-OC); one of these antibodies is attached to the assay plate and the other is peroxidase-linked. Direct measurement of Glu-OC by the Undercarboxylated Osteocalcin (Glu-OC) EIA Kit provides accurate bone metabolism data without the need for radioactivity. Furthermore, the Undercarboxylated Osteocalcin (Glu-OC) EIA Kit can be used in conjunction with the Gla-Type Osteocalcin (Gla-OC) EIA Kit (Cat. #MK111) to obtain more complete bone metabolism data.

The Gla-type Osteocalcin EIA Kit is an in vitro enzyme immunoassay (EIA) kit for quantitative determination of human Gla-OC in serum, cultured cell extracts, cell culture supernatants, and other biological fluids.
