Description
Growth/differentiation factors (GDF-1 to GDF-15) are members of the BMP family of TGF-beta superfamily proteins. At the amino acid level, mature human GDF-7 shares 85% and 88% aa sequence identity with mature GDF-7 in mouse and rat. They are produced as inactive preproproteins which are then cleaved and assembled into active secreted homodimers. GDF dimers are disulfide-linked with the exception of GDF-3 and -9. GDF proteins are important during embryonic development, particularly in the skeletal, nervous, and muscular systems. GDF-7 is involved in tendon and ligament formation and repair. GDF-7 also regulates bone formation, mesenchymal stem cell differentiation, neuronal differentiation, and axon guidance in the central nervous system.

>95% by SDS-PAGE and HPLC analyses.
Biological Activity
The ED50 as determined by inducing alkaline phosphatase production of mouse ATDC5 cells is less than 0.5 μg/mL, corresponding to a specific activity of > 2000 IU/mg. Fully biologically active when compared to standard.
Endotoxin
< 0.1 EU per 1μg of the protein by the LAL method.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in 30% Acetonitrile and 0.1% TFA.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
