Recombinant Human Thyroid Stimulating Hormone Beta (β-TSH) Protein

Thyrotropin-stimulating hormone (TSH) is a noncovalently linked glycoprotein heterodimer and is part of a family of pituitary hormones containing a common alpha subunit (TSHA) and a unique beta subunit that confers specificity.Using bovine TSHB cDNA as probe, Hayashizaki et al. (1985) cloned TSHB from human liver and leukocyte genomic DNA libraries. Human TSHB encodes a deduced protein consisting of a 20-amino acid signal sequence, a mature protein of 112 amino acids, and a C-terminal extension of 6 hydrophobic amino acids. Wondisford et al. (1988) also cloned the human TSHB gene.Wondisford et al. (1988) determined that the TSHB gene contains 3 exons, the first of which is noncoding. The rat TSHB gene also contains one 5-prime noncoding exon, whereas the mouse Tshb gene contains 3.
 

Reconstitute in PBS or others.
 

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
 

Store it under sterile conditions at -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. Samples are stable for up to twelve months from date of receipt at -80℃.
 

Lyophilized from sterile 20mM PB，240mM NaCl，PH6.32.
