Source:
Escherichia coli
Animal-free reagent and laboratory
Manufactured and tested under GMP guideline

Endotoxin level:
<0.1 EU per 1 μg of the protein by the LAL method.

Activity:
Measure by its ability to induce IL-8 secretion in human PBMCs. The ED50 for this effect is 1-5 ng/mL.

Purity:
>95% as determined by SDS-PAGE analysis.
Purified by Ni-NTA chromatography.

Formulation:
The protein was lyophilized from a solution containing 1X PBS, pH 8.0.

Reconstitution:
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. This product is stable for one year upon receipt, when handled and stored as instructed. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C. Avoid repeated freeze/thaw cycles.

Note:
Please use within one month after protein reconstitution.
