Applicable Applications for INHBB cell lysate
Western Blot (WB)
Application Notes
WB: Use at an assay dependent dilution.
Species
Human
Recommend Usage
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200uL pure water and boil for 2-5 min.
Sequence Construction
A DNA sequence encoding the pro form of human INHBB (NP_002184.2) (Met 1-Ala 407) was expressed, fused with a polyhistidine tag at the C-terminus.
Preparation Method
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Preparation and Storage
Store at 4 degree C for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80 degree C for up to twelve months. Avoid repeated freeze-thaw cycles.
Samples are stable for up to twelve months from date of receipt.
Related Product Information for INHBB cell lysate
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 beta subunits, betaA betaA (activin A), betaB betaB (activin B), or betaA betaB (activin AB). Inhibin is composed of an alpha and one of two beta subunits, betaA (inhibin A) or betaB (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.

This Human Inhibin beta B overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Inhibin beta B protein from the overexpression lysate was verified.

NCBI Description

The inhibin beta B subunit joins the alpha subunit to form a pituitary FSH secretion inhibitor. Inhibin has been shown to regulate gonadal stromal cell proliferation negatively and to have tumour-suppressor activity. In addition, serum levels of inhibin have been shown to reflect the size of granulosa-cell tumors and can therefore be used as a marker for primary as well as recurrent disease. Because expression in gonadal and various extragonadal tissues may vary severalfold in a tissue-specific fashion, it is proposed that inhibin may be both a growth/differentiation factor and a hormone. Furthermore, the beta B subunit forms a homodimer, activin B, and also joins with the beta A subunit to form a heterodimer, activin AB, both of which stimulate FSH secretion.

Uniprot Description

INHBB: Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins. Belongs to the TGF-beta family.

Product Notes

The INHBB inhbb (Catalog #AAA8114155) is a Cell Lysate produced from HEK293 Cells and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 390aa. AAA Biotech's Inhibin beta B can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: Use at an assay dependent dilution. Researchers should empirically determine the suitability of the INHBB inhbb for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Met1-Ala40 7. It is sometimes possible for the material contained within the vial of "Inhibin beta B, Cell Lysate" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
