제품 설명
Growth Differentiation Factor-5 (GDF-5; also called BMP-14 and CDMP-1) is a member of the BMP family of TGF-beta superfamily proteins. Human GDF-5, -6, and -7 are a defined subgroup of the BMP family. GDF-5 is synthesized as a homodimeric precursor protein consisting of a 354 amino acid (aa) N-terminal pro-region and a 120 aa C-terminal mature peptide. Mature human GDF-5 shares 99% aa sequence identity with both mature mouse and rat GDF-5. GDF-5 signaling is mediated by formation of a heterodimeric complex consisting of a type 1 (BMPR-IB) and a type II (BMPR-II or Activin RII) serine/threonine kinase receptor which results in the phosphorylation and activation of cytosolic Smad proteins (Smad1, 5, and 8). Similar to other BMP family proteins, GDF-5 signaling is antagonized by Noggin. GDF-5 is involved in multiple developmental processes including limb generation, cartilage development, joint formation, bone morphogenesis, cell survival, and neuritogenesis.

Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Purity | > 95% by SDS-PAGE and HPLC analyses. |
Biological Activity | The ED50 as determined by inducing alkaline phosphatase production of murine ATDC5 cells is less than 1.0 μg/mL, corresponding to a specific activity of > 1000 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 4 mM HCl to a concentration of 0.1-1.5 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions. |
The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
