| Cat. No. : |
MSTN-34H |
| Description : |
Myostatin (also known as growth differentiation factor 8, abbreviated "GDF8") is a secreted TGF beta protein family member that inhibits muscle differentiation and growth. Myostatin is produced primarily in skeletal muscle cells, circulates in the blood and acts on muscle tissue, by binding a cell-bound receptor called the activin type II receptor. In humans, myostatin is encoded by the MSTN gene. |
| Species : |
Human |
| Source : |
E.coli |
| Form : |
Lyopohilized with no additives. |
| Purity : |
Purity Greater than 95% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE. |
| Bio-activity : |
Recombinant Human Myostatin is fully biologically active when compared to standard. The ED50 as determined by the inhibition of the prolifiration of MPC-11 cells is < 20 ng/ml. |
| Physical Appearance : |
Sterile Filtered white lyophilized (freeze-dried) powder. |
| Solubility : |
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions. |
