Cat#: | RP-2308R |
Product Name: | Recombinant Rat FGF21 Protein |
Synonym: | Fibroblast growth factor 21, FGF-21. |
Description: | FGF 21 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 180 amino acids and having a molecular mass of 19.7kDa. The FGF 21 is purified by proprietary chromatographic techniques. |
Source: | E.coli |

Purity: | >95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Bioactivity: | Fully biologically active when compared to standard. The ED50 determined by a cell proliferation assay using murine NIH/3T3 cells is less than 700 ng/ml, corresponding to a specific activity of > 1.4 × 1000 IU/mg in the presence of 5µg/ml of rMuKlotho-bet |
Formulation: | Lyophilized from a 0.2µm filtered concentrated solution in 1×PBS, pH 7.4. |
Stability: | Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃ |
Reconstitution: | It is recommended to reconstitute the lyophilized FGF 21 Rat Recombinant in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Storage: | Lyophilized FGF 21 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF 21 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. |
