FSH is a member of a superfamily of proteins, all structurally related. which includes luteinizing hormone (LH), chori->inlc gonadotropin, and thyroid-stimulating hormone (TSH). It is u heterodimer, the a subunit contains 92 amino acids, and the subunit contains 111 amino acids. The protein IS rather heavily glycosylated and has a molecular mass of approximately 33 kDa. The traditional source for isolation t l FSH was postmenopausal urine, which provided a preparation that was less than 3% pure and wa.s signiricantly contaminated by LH. The recombinant human FSH (rhFSH) is produced in a mammalian cell line, the CHO.
