Cat. No.: HY-P700027AF
COA Handling Instructions

Bone morphogenetic protein 4 (BMP-4) is a polymorphic ligand protein belonging to the TGF-β family, which is involved in the circulation of the vascular system and can activate receptors on vascular cells. BMP-4 binds to type I receptors (ALK-2/-3/-6) and type II receptors (BMPR2, ACVR2A) to increase plaque formation and promote oxidative stress, endothelial dysfunction, and osteogenic differentiation through its pro-inflammatory and pro-atherogenic effects. Animal-Free BMP-4 Protein, Human (His) has a total length of 106 amino acids (K303-R408), is expressed in E. coli cells with a 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

Bone morphogenetic protein 4 (BMP-4) is a polymorphic ligand protein belonging to the TGF-β family, which is involved in the circulation of the vascular system and can activate receptors on vascular cells[1]. BMP-4 binds to type I receptors (ALK-2/-3/-6) and type II receptors (BMPR2, ACVR2A)[2] to increase plaque formation and promote oxidative stress, endothelial dysfunction, and osteogenic differentiation through its pro-inflammatory and pro-atherogenic effects[3]. Animal-Free BMP-4 Protein, Human (His) has a total length of 106 amino acids (K303-R408), is expressed in E. coli cells with a C-terminal His-tag.

Background

Bone Morphogenetic Protein 4 (BMP-4) is a ligand protein with pleiotropic, belongs to TGFβ family. BMP-4 involves in the vasculature circulation and can activate receptors on vascular cells[1].
BMP-4/TGFβ signaling can be terminated by inhibitory SMADs including SMAD6 and SMAD7, which are activated and induced by BMP signaling and switch off BMP signaling via multiple mechanisms[4].
BMP-4 is widely found in different animals, while the sequence in human is highly similar to Rat (96.81%), and mouse (97.54%).
BMP-4 is expressed by endothelial cells (ECs) in response to hypoxia and promotes vascular SMC proliferation. Therefore it inhibits the proliferation of smooth muscle cells (SMCs) isolated from the proximal pulmonary artery while induces proliferation of SMCs isolated from distal pulmonary arteries[5].
BMP-4 appears to be a marker and driver of vascular calcification, particularly in atherosclerosis[6].
BMP-4 induces angiogenesis, endothelial cells (ECs) proliferation, and migration[7].
BMP-4 is differentially expressed in calcified atherosclerotic plaques[8], serves as the linkers between atherosclerotic vascular calcification with mechanisms of normal bone formation[9].
BMP-4 increases plaque formation via their pro-inflammatory and pro-atherogenic effects, promoting oxidative stress, endothelial dysfunction and osteogenic differentiation[3].

In Vitro

BMP-4 (1 ng/mL for 4-5 d; 1 ng/mL for 3-4 d; 1 ng/mL for 2 d) induces a synchronous wave of differentiation occurred, characterized by flattened, enlarged cells with reduced proliferation[1].
BMP-4 (1 ng/mL; 7 d) initiates human embryonic stem cell differentiation to trophoblast[1].
BMP4 (1 or 1 ng/mL; 24 h) significantly increases the number of mesenchymal condensations by approximately 5%[11].

Biological Activity

Measure by its ability to induce alkaline phosphatase production by ATDC5 cells. The ED50 for this effect is <0.58 ng/mL.

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
