BMP-4 activity assay

The activity was determined by the dose-dependent induction of alkaline phosphatase production in the ATDC-5 cell line (Mouse chondrogenic cell line) using pNPP as chromogenic substrate.

BMP-4 purity

The protein was resolved by SDS- polyacrylamide gel electrophoresis and the gel was stained with Coomassie blue. R represents reducing conditions and NR represents non-reducing conditions.

Stability and Reconstitution

Stability and Storage:
Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20oC) and (-80oC). Upon reconstitution we recommend that the solution can be stored at (4oC) for short term or at (-20oC) to (-80oC) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.


Reconstitution:
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 4 mM HCl containing 0.1% endotoxin-free recombinant human serum albumin (HSA).

Product Description

Product Description:

Animal-free Recombinant Human BMP-4 is expressed in human 293 cells as a disulfide linked homodimeric glycoprotein with an apparent molecular mass of 34 kDa. This cytokine is produced in a serum-free, chemically defined media.



Background:

Bone morphogenetic protein-4 (BMP4), also known as BMP2B and DVR4, belongs to the TGF-beta family. BMPs have been shown to promote astroglial differentiation both in vitro and in vivo. BMP4 can also induce cartilage and bone formation (PMID 16234975). Xeno-free Recombinant Human BMP-4 is expressed in human 293 cells as a disulfide linked homodimeric glycoprotein with an apparent molecular mass of 34 kDa. 



Synonyms:
BMP-2B, DVR4 BMP-4, BMP4, BMP 4
