TSH Alpha and Beta Subunit
Product Specification:
The alpha and beta subunit of TSH are two dissimilar protein chains that together compose TSH. They are produced by chemically cleaving the whole molecule. The alpha chain is identical to the alpha subunit of hCG, LH, and FSH. The beta subunit gives TSH its distinct biological activity.
