Human Bone Morphogenetic protein-4 Recombinant
Categories: Recombinant Human CytokinesTGF-beta familyTGF-beta family$70.00 – $3,550.00
Description
Accession
P12644
Source
Optimized DNA sequence encoding Human Bone Morphogenetic protein-4 mature chain was expressed in Escherichia Coli.
Molecular weight
Recombinant BMP-4 is a homodimeric protein consisting of 2x106 amino acid residue subunits, and migrates as an approximately as a 12 kDa protein under reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) was determined by its ability to induce alkaline phosphatase productionin mouse ATDC5 chondrogenic and was found to be in the range of 0.1-0.2 ug/ml.
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant BMP-4 was lyophilized from a 0.2 μm filtered PBS, pH 7.2
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° -8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Effects of Activin A on paraxial mesodermal differentiation of mouse iPS cells.
- The cultures also contained BMP4 (10 ng/ml), IGF-1 (10 ng/ml), LiCl (5 mM), and Shh (10 ng/ml).
Loss of REX1 within the pluripotent population primes cells for differentiation.
- n = 3 E) Fold enrichment of the percentage of GATA4 positive endoderm cells generated from TRA+VEN− cells relative to those from TRA+VEN+ population after 3 days of treatment with Activin A and BMP4 in low serum media, as observed by immunocytochemistry.

2.6. Monolayer-Based hiPSC Differentiation towards Definitive Endoderm
-
For DE differentiation, hiPSCs were plated onto Matrigel-coated dishes and cultured in medium'>FDTA medium supplemented with 10 
μ M Rock-inhibitor Y-276342 for 24 hours. - When the cells reached about 75% confluence, medium was changed to PMI 1640 medium containing 2% FBS with 500 nM IE1 , 3 
μ M I99021 , 5 μ M LY294002 , and 10 ng/mL BMP4 for 24 hours. - Then, medium was changed to RPMI 1640 medium containing 2% FBS and supplemented with 500 nM IDE1 and 5 
μ L LY294002 for two days. - From day 3 on, cells were cultured in RPMI 1640 supplemented with 500 nm IDE1, 5 
µ M LY294002, and 50 ng/mL FGF2. - The respective figure contains an experimental outline illustrating detailed culture conditions and treatment regimens [
Differentiation of ES and iPS Cells
- For definitive endoderm (E) differentiation, mouse ES/iPS cells were cultured on M15 cells with added recombinant human activin-A at 10 ng/ml and/or human bFGF at 5 ng/ml for 3–7 d, as indicated.
- They were subsequently analyzed using flow cytometry to assay for DE or Cer1 expression 5, 0.5 × 105, or 1.0 × 105 cells/well on a matrigel (BD) pre-coated 96-well plate.
- For neuroectoderm differentiation, ES cells were cultured on M15 cells in a differentiation medium supplemented with 10 µM SB431542 (a TGFβ inhibitor)
