Thyroid Stimulating Hormone (TSH)
| Catalog Numbers: | TSH Standard Grade – 190S TSH High Purity – 190A |
Product Specification:
TSH is a glycoprotein having two subunits. The alpha subunit is similar to those of FSH, HCG, and LH. The beta subunit is different from the other hormones and confers its biochemical specificity. TSH is secreted by the basophilic cells of the anterior pituitary. TSH is responsible for regulating thyroid function. TSH is available as whole molecule standard (50%) and High purity (95%) grades, or as alpha and beta subunits.
