Introduction
Fibroblast growth factor 20 (FGF20) belongs to the FGF gene family and member of FGF-9 subfamily (based upon its structure). Human FGF20 has several receptors which include FGF R1c, FGF R2c, FGF R3b, FGF R3c and FGF R4. FGF20 is expressed a various cells, including dopaminergic neurons, fibroblasts, keratinocytes and breast epithelium, and numerous sites in the fetus.
Description
FGF20 Human Recombinant (1-211) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 217 amino acids and having a molecular mass of 24kDa.
The FGF-20 is fused to a 6 amino acid His tag [HHHHHH] at N-terminus and purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2µm filtered solution in MOPS, (NH4)2SO4, DTT and EDTA.
Solubility
It is recommended to reconstitute the lyophilized FGF-20 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized FGF20 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF-20 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity
Greater than 97.0% as determined by SDS-PAGE.
