Fibroblast Growth Factor-21 Human Recombinant
Fibroblast Growth Factor -21 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 181 amino acids and an N-terminal Methionin (bold), having a molecular weight of 19.7 kDa (calculated). The amino acid sequence of the recombinant human FGF21 is 100% homologous to the amino acid sequence of the human FGF21 without signal sequence.
The FGF-21 is purified by proprietary chromatographic techniques.

Formulation
Filtered (0.4 um) and lyophilized from 0.5 mg/ml in 20mM TRIS, 20mM NaCl, pH 7.5.
Physical Appearance
Sterile Filtered white lyophilized powder.
Purity
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility
It is recommended to reconstitute the lyophilized Fibroblast Growth Factor-21 Human Recombinant sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Stability
Lyophilized FGF-21 Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Fibroblast Growth Factor 21 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
