FGF 19 Human, His

Fibroblast Growth Factor-19 Human Recombinant, His Tag

Fibroblast Growth Factor -19 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 206 amino acids and having a molecular mass of 23 kDa. The amino acid sequence of the recombinant human FGF19 is 100% homologous to the amino acid sequence of the human FGF19 without signal sequence and contains his tag at N-terminal The FGF-19 is purified by proprietary chromatographic techniques.

Add deionized water to a working concentration approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by appropriate sterile filter before using it in the cell culture.

Source

Escherichia Coli.

Stability

Lyophilized FGF-19 Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Fibroblast Growth Factor-19 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.

Synonyms
