Source:
Escherichia coli

Purity:
>98% as determined by SDS-PAGE. Ni-NTA chromatography

Endotoxin Test:
<0.1 EU/μg by LAL method

Bioactivity (ED50):
1.339-1.976 ng/mL measured by its ability to induce 3T3 cells proliferation

Suggested application:
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Storage: 
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. The protein was lyophilized from a solution containing 1XPBS, pH 8.0. Please use finished within one month after protein reconstitution.
