BMP-2 induces ALP production in mouse chrondrogenic cell line ATDC5. -
Stability test for Human/Mouse/Rat BMP-2:BMP-2 was aliquoted in 4 mM HCl at 0.1 mg/ml. The aliquots were treated as follows: at 4°C (control), room temperature (RT), and 37°C for one week, and one aliquot was freeze/thawed four times (4x free-thaws). After this procedure, the samples were tested for their ability to induce alkaline phosphatase in the mouse chrondrogenic cell line ATDC5.
Bone morphogenetic protein 2 (BMP-2) belongs to the TGF-β superfamily. Like other members of BMP family, BMP-2 is synthesized as an inactive propeptide precursor which dimerizes and then it is further processed into mature form by proprotein convertases (PCs). Some evidence indicated that PC5/6A and Factor VII-activating protease (FSAP) are involved in maturation of BMP-2. Mature BMP-2 is a 26 kD protein composed of 114 amino acids, forming three intramolecular and one intermolecular disulfide bond. BMP-2 forms homodimer or heterodimer with other BMP proteins, including BMP-4, BMP-6 and BMP-7. BMP-2 signal through heterodimeric serine/threonine kinase receptors composed of a type I (BMPR1a/ALK3, BMPR1b/ALK6, ActRIa/ALK2) and a type II (BMPR2, ACVR2a/ActRIIA, ACVR2b/ActRIIB). BMP-2 binds to the type I receptor with high affinity, in turn recruits the type II receptor. BMP-2 stimulation initiates receptor shutting, leading to receptor clustering and activation of the downstream signaling. BMP-2 signals via canonical Smad or other downstream kinase, such as p38 and JNK in a context-dependent manner. BMP-2 is involved in several processes, including cartilage and bone formation, differentiation, and embryogenesis. BMP-2 induces osteogenic differentiation in human mesenchymal stem cells and myogenic cells. BMP-2 induces cartilage repair and remodeling by stimulating chondrocyte proliferation and expression of matrix proteins. BMP-2/BMP-7 heterodimer is more potent in the induction of bone formation in vivo than BMP-2 homodimer. BMP-2-deficiency leads to embryonic lethality with abnormal cardiac development, malformation of the amnion/chorion, severe chondrodysplasia, and defects in myocardial patterning, suggesting that BMP-2 mediates organ morphogenesis. Noggin is an antagonist to reverse BMP-2-mediated effect and its expression is induced by BMP-2 in osteoblasts as a negative feedback loop. In addition, BMP-2 stimulates epithelial to mesenchymal cell transformation through TGF-β type III receptor.

- What is the specific activity or ED50 of my recombinant protein?
-
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
- Have your recombinants been tested for stability?
-
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
- Does specific activity of a recombinant protein vary between lots?
-
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
-
Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
