蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 28.4 kDa. The protein migrates as 43-48 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳（SDS-PAGE）
Human TSH alpha/beta Heterodimer, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).
背景（Background）
Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, or abbreviated TSH) is a pituitary hormone that stimulates. It is a glycoprotein hormone produced by thyrotrope cells in the anterior pituitary gland, which regulates the endocrine function of the thyroid. Thyroid stimulating hormone consists of two subunits called alpha and beta. The alpha and beta subunits are bound together to produce the active form of the hormone. The α subunit is thought to be the effector region responsible for stimulation of adenylate cyclase (involved the generation of cAMP).The β (beta) subunit (TSHB) is unique to TSH, and therefore determines its receptor specificity.
