Osteocalcin ELISA Kit

  • Created on the 1 February, 2017.

BACKGROUND

Osteocalcin (OST) which is also called bone Gla protein (B.G.P) is a 49 amino-acids peptide which contains three residues of gamma carboxyl glutamic acids and is 5800 Da in molecular weight. It is synthesised in the bone by the osteoblasts where after its production it is partly incorporated in the bone matrix, the rest of it is found to be circulating in blood. There are a large number of publications which show a direct correlation between the rate of bone formation and the levels of circulating osteocalcin but the exact physiological function is yet still unclear.

In clinical application determining the levels of osteocalcin in blood is helpful in many cases for example when:
(a). monitoring bone metabolism during the perimenopause and post-menopause.
(b). monitoring bone metabolism in patients that have growth hormone deficiency, chronic renal failure, hypothyroidism and hyperthyroidism.
(c). identifying women that are at potential risk of developing osteoporosis.
(d). monitoring bone metabolism during treatment of premenopausal women with LH-RH agonists and hormone replacement therapy.

INTENDED USE

Osteocalcin ELISA kit is a reliable quantitative procedure for measuring osteocalcin (OST) in human serum. This assay has a sensitivity detection limit of 0.8 ng/ml.

SENSITIVITY

The minimum sensitivity detection limit of osteocalcin (OST) using this osteocalcin ELISA kit was approximately 0.8 ng/ml. The dynamic assay range for this kit is 1.9 – 90.0 ng/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
