ED50 is 0.903 ng/mL, measure by the dose-dependant proliferation of NR6R-3T3 cells, corresponding to a Specific Activity of 1.1 x 107Units/mg.
Storage Buffer:
Protein(1 mg/mL) was lyophilized from a solution containing 5mM Na2PO4, pH7.5, 50mM NaCl. Reconstitute the lyophilized powder in ddH2O to 101 ug/mL.
Storage Instruction:
Lyophilized protein at room temperature for 3 weeks, should be stored at -20°C. Protein aliquots at 4°C for 2-7 days and should be stored at -20°C to -80°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze/thaw cycles.
