Human CG alpha / CGA Protein, His Tag

分子别名(Synonym)

CGA,TSH-alpha,LSH-alpha,CG-alpha,FSH-alpha

表达区间及表达系统(Source)

Human CG alpha, His Tag (CGA-H52H2) is expressed from human 293 cells (HEK293). It contains AA Ala 25 - Ser 116 (Accession # AAH20782).

Predicted N-terminus: Ala 25

蛋白结构(Molecular Characterization)

Online(Ala 25 - Ser 116) AAH20782

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 12.1 kDa. The protein migrates as 22-26 kDa 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)

>92% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human CG alpha, His Tag (Cat. No. CGA-H52H2) SDS-PAGE gel

Human CG alpha, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 92%.

背景(Background)

Chorionic gonadotrophin subunit alpha (CGA),a member of the glycoprotein hormones subunit alpha family, is also known as glycoprotein hormones alpha chain, choriogonadotropin alpha chain, follicle-stimulating hormone alpha chain (FSH-alpha), luteinizing hormone alpha chain (LSH-alpha) and thyroid-stimulating hormone alpha chain (TSH-alpha). The hormones human chorionic gonadotropin (hCG), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) are dimers consisting of alpha and beta subunits that are associated noncovalently. The alpha subunits (CGA) of these four human glycoprotein hormones are nearly identical, however, their beta chains are unique and confer biological specificity.
