Calcitonin Description
Rabbit anti-human calcitonin is a purified immunoglobulin fraction of rabbit serum. Contaminating antibodies have been absorbed by solid-phase absorption. The antibody reacts with human calcitonin and labels C-cells in normal thyroid. It is particularly useful in differentiating medullary carcinoma from papillary and follicular thyroid cancer. When used in conjunction with an anti-thyroglobulin antibody, most medullary carcinomas are positive for calcitonin, and is usually negative for most papillary and follicular types of thyroid cancer.
