General description
Osteocalcin (UniProt: P02818; also known as Bone Gla protein, BGP, Gamma-carboxyglutamic acid-containing protein) is encoded by the BGLAP gene (Gene ID: 632) in human. Osteocalcin is a member of the osteocalcin/matrix Gla protein family and can constitute 1 to 2% of the total bone protein. It is synthesized by osteoblasts and is a major component of the non-collagenous bone matrix. Osteocalcin is synthesized with a signal peptide (aa 1-23) and a propeptide (aa 24-51) that are subsequently cleaved off to generate the active secreted form of osteocalcin (aa 52-100). Osteocalcin displays a high affinity for calcium and binds strongly to apatite. Sixty to ninety percent of de novo synthesized osteocalcin is incorporated into the bone matrix where it binds to hydroxyapatite during matrix mineralization. The remainder of the osteocalcin is released into the circulation where it can be a sensitive marker of bone formation. Serum osteocalcin is almost exclusively derived from the bone formation with little or no contribution from the resorption process. A major feature of osteocalcin is the presence of 3 vitamin K-dependent g-carboxyglutamic acid (Gla) residues, which are found in the first helical region and interact with the inter-calcium spacing in the HAP lattice. In humans, the percentage of the circulating osteocalcin, which is not g-carboxylated is used as a biomarker of vitamin K status. Osteocalcin expression in osteoblasts is stimulated by insulin and adiponectin and osteocalcin enhances insulin sensitivity and differentiation in muscle. Serum osteocalcin is elevated in diseases characterized by increased bone turnover such as osteoporosis, hyperparathyroidism, and Paget′s disease, and low in conditions associated with low bone turnover such as hypoparathyroidism and growth hormone deficiency. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 2J18 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Osteocalcin. It targets an epitope within 21 amino acids from the C-terminal region.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
