Cat. No.: HY-P700031AF
COA Handling Instructions

BMP-8 is a pleiotropic ligand protein act as a reproductive system regulator, enriched in the ovary. BMP-8 is encoded by a pair of genes BMP8A and BMP8B, belonging to TNF-β family. BMP-8A activates the SMAD1/5/8 and the SMAD2/3 pathways in granulosa cells, to inhibit gonadotropin-induced progesterone production and steroidogenesis-related gene expression. BMP-8A also involves in Nrf2 phosphorylation in cancer cells to promote survival and drug resistance. BMP-8a Protein, Human is 402 a.a. with 2 glycosylation domains. Animal-Free BMP-8a Protein, Human (His) is a animal free recombinant human protein produced in E. coli cells, with 139 a.a. (A264-H402) and C-terminal His-tag.

Animal-free recombinant proteins offer high consistency and stability, whithout using or contacting of any animal-derived materials and reagents.

Description

BMP-8 is a pleiotropic ligand protein act as a reproductive system regulator, enriched in the ovary. BMP-8 is encoded by a pair of genes BMP8A and BMP8B, belonging to TNF-β family[1]. BMP-8A activates the SMAD1/5/8 and the SMAD2/3 pathways in granulosa cells, to inhibit gonadotropin-induced progesterone production and steroidogenesis-related gene expression[1]. BMP-8A also involves in Nrf2 phosphorylation in cancer cells to promote survival and drug resistance[2]. BMP-8a Protein, Human is 402 a.a. with 2 glycosylation domains. Animal-Free BMP-8a Protein, Human (His) is a animal free recombinant human protein produced in E. coli cells, with 139 a.a. (A264-H402) and C-terminal His-tag.

Background

"BMP-8 is a pleiotropic ligand protein act as a reproductive system regulator. BMP-8 is encoded by a pair of genes, BMP8A and BMP8B, belonging to TNF-β family. GMP-8 initiates the canonical BMP signaling cascade by associating with type I receptor BMPR1A and type II receptor BMPR2. Both BMP8A and BMP8B are enriched in the ovary and activate canonical BMP signaling in different cells, including spermatogonia, P19 and 293T cells[1]. BMP-8 is widely found in different animals, while the sequences of BMP-8A and BMP-8B in human are highly different from Mouse with similarities of 85.96% and 74.44%, respectively.
As for BMP8A, which is mainly secreted by granulosa cells within growing ovarian follicles. BMP8A encodes a secreted ligand of the TGF-β superfamily of proteins to bind various TGF-beta receptors, leading to recruitment and activation of SMAD family transcription factors and regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer[2]. BMP-8A protein activates the SMAD1/5/8 and the SMAD2/3 pathways in granulosa cells, to inhibit gonadotropin-induced progesterone production and steroidogenesis-related gene expression[1]. BMP8A protein plays a role in development of the reproductive system by sustaining spermatogenesis by activating both SMAD1/5/9 and SMAD2/3 in spermatogonia. BMP-8A protein also activates Nrf2 and Wnt pathways in clear cell renal cell carcinoma (ccRCC) to promote cell proliferation and inhibit apoptosis[2].
As for BMP8B, which protein is secreted by brown/beige adipocytes and enhances energy dissipation, serves as an interconnected regulator of neuro-vascular remodeling in AT and is potential targets in obesity[3]. BMP8B increases brown adipose tissue thermogenesis through both central and peripheral actions[4]. Thus BMP8B contributes to adrenergic-induced remodeling of the neuro-vascular network in adipose tissue, therefore through the adipocytes to 1) secrete neuregulin-4 (NRG4), which promotes sympathetic axon growth and branching in vitro, and 2) induce a pro-angiogenic transcriptional and secretory profile that promotes vascular sprouting[3]. BMP8B also involve in activation of caspase-3 and -9, and apoptosis to inhibit pancreatic cancer cell growth[5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
