Recombinant Human GDF-5

Growth differentiation factor 5 (cartilage-derived morphogenetic protein-1), also known as GDF5 is a member of the bone morphogenetic protein (BMP) family and the TGF-beta superfamily. GDF5 is expressed in the developing central nervous system.¹ It increases the survival of neurones that respond to a neurotransmitter called dopamine, and is a potential therapeutic molecule associated with Parkinson's disease.²

Human GDF-5 is fully biologically active when compared to standard. Induction of alkaline phosphatase acrtivity in ATDC5 cells: EC50 = 40Nm.

The lyophilized protein should be stored desiccated at -20°C. The reconstituted protein can be stored for at least one week at 4°C. For long-term storage of the reconstituted protein, aliquot into working volumes and store at -20°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
