The specific activity was determined by the dose-dependent stimulation of the proliferation of 4MBr-5 cells (monkey epithelial cell line) and is typically 10-40ng/ml.
The KGF was lyophilized from 1mg/ml in 1xPBS.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95% as obsereved by SDS-PAGE.
It is recommended to reconstitute the lyophilized KGF in sterile water not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Although lyophilized KGF is stable at room temperature for 3 weeks, it should be stored desiccated below -18oC. Upon reconstitution KGF should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
