FGF4 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 182 amino acids and having a molecular mass of 19.8kDa.
The FGF4 is purified by proprietary chromatographic techniques.
The FGF4 protein was lyophilized with 2xPBS, pH 7.4.
It is recommended to reconstitute the lyophilized FGF4 Human Recombinant sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Please prevent freeze-thaw cycles.
