Human recombinant IL-27 EBI3 (Interleukin-27 EBI3) protein, AF

Interleukin 27 EBI3 (IL-27 EI3) predicts a molecular mass of 23.4 kDa. IL-27 is a heterodimeric cytokine that is encoded by Epstein-Barr virus-induced gene 3 (EBI3) and IL-27p28. It is expressed by antigen presenting cells and interacts with a specific cell-surface receptor complex known as IL-27 receptor (IL-27R) .

Applications

Cell Culture

Purification

>95% as determined by SDS-PAGE.

Endotoxin

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

Bioactivity

Measure by its ability to induce TF-1 cells proliferation using a concentration range of 20-200 ng/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us.

Reconstitution

Centrifuge at 3000 rpm for 5 mins before opening. 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 at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.

Molecular Weight

The protein has a calculated MW of 24.25 kDa. The protein migrates as 25 kDa under reducing condition (SDS-PAGE analysis) .

Storage Conditions

Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
