Inhibin beta B Protein, Human, Recombinant (His Tag)

Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. The activin and inhibin protein complexes are both dimeric in structure, and, in each complex, the two monomers are linked to one another by a single disulfide bond. Activin is composed of two β subunits, βA βA (activin A), βB βB (activin B), or βA βB (activin AB) . Inhibin is composed of an alpha and one of two β subunits, βA (inhibin A) or βB (inhibin B) . Activins are produced in many cell types and organs, such as gonads, pituitary gland, and placenta. In the ovarian follicle, activin increases FSH binding and FSH-induced aromatization. It participates in androgen synthesis enhancing LH action in the ovary and testis. In the male, activin enhances spermatogenesis. Also, Activin plays a role in wound repair and skin morphogenesis. Activin is strongly expressed in wounded skin, and overexpression of activin in the epidermis of transgenic mice improves wound healing and enhances scar formation. Activin also regulates the morphogenesis of branching organs such as the prostate, lung, and kidney. There is also evidence showed that lack of activin during development results in neural developmental defects.

Measured by its binding ability in a functional ELISA.Immobilized human INHBB-His (Cat: PH50606M2) at 10 μg/ml (100 μl/well) can bind biotinylated mouse FLRG-His (Cat: 10591-M08H) with a linear range of 0.031-0.125 μg/ml.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The secreted pro form of human INHBB comprises 390 amino acids with a predicted molecular mass of 43.7 kDa. As a result of glycosylation, the apparent molecular mass of rhINHBB is approximately 17, 42 and 55 kDa in SDS-PAGE under reducing conditions, corresponding to the mature form, pro peptide and pro form respectively.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
