Source

E. coli

Field of Research

Cancer Biology, Immunology & Inflammation, Metabolism Research, Neuroscience, Signal Transduction

Purity

Greater than 98% by SDS-PAGE gel and HPLC analyses.Endotoxin level is less than 0.1 ng per μg (1EU/μg) .

Bioactivity

The ED50 was determined by the dose - dependant proliferation of the RPMI 8226 cells. The expected ED50 for this effect is 15.0 - 20.0 ng/mL.

Form

Lyophilized

Storage Conditions

The lyophilized Visfatin recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Visfatin is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Visfatin recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
