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