Only 60–90% of de novo synthesized osteocalcin is incorporated into the bone matrix binding to hydroxy apa- tite during matrix mineralization order cheap zyprexa treatment lichen sclerosis. The remainder enters the circulation where it may be assayed as a sensitive marker for bone formation buy discount zyprexa on-line treatment hepatitis c. Serum osteocalcin is derived almost exclu- sively from bone formation buy norvasc 5 mg with mastercard, rather than resorption. Serum osteocalcin is increased in diseases marked by elevated bone turnover, such as osteoporosis, hyperparathyroidism, and Paget disease, and is decreased in conditions associated with low bone turnover, including hypoparathyroidism and growth hormone defciency.

A mouse monoclonal antihuman progesterone receptor antibody that specifcally recognizes the A and B forms of the receptor in Western blot purifed recombinant receptor, normal endo- metrium, and cell lysates of the progesterone receptor-rich T47D human breast carcinoma cell line. No cross-reactivity was found with androgen receptor, estrogen receptor, or glu- cocorticoid receptor. The antibody binds an epitope found between amino acids 165 and 534, in the N-terminal trans- activation domain of the progesterone receptor molecule. Various tumors of the female reproductive tract have been shown to express progesterone receptor. Antihuman thyroglobulin is a rabbit antibody that reacts with human thyroglobulin. It can also be used to differentiate small-cell lung carcinoma from lymphoid infltrates.
