GDF-7 Recombinant Protein

GDF-7 belongs to the TGF-β superfamily of growth and differentiation factors. It is expressed selectively by roof plate cells that are located in the developing embryonic central nervous system, and has been shown to influence the neuronal identity of cells within the central nervous system. GDF-7 has also been implicated in the formation, maintenance, and repair of certain cartilage and ligament tissue. Recombinant human GDF-7 is a 28 kDa disulfide linked homodimer containing two 129 amino acid residues.

The lyophilized GDF-7 recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted GDF-7 stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing GDF-7 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
