Swine recombinant IL-10 (Interleukin-10) protein, AF

Interleukin 10 (IL-10) is a 17.54 kDa cytokine with 158 amino acid residues and is also known as human cytokine synthesis inhibitory factor (CSIF) . IL-10 is an anti-inflammatory cytokine that is mainly secreted from monocytes, lymphocytes, and mast cells. IL-10 participates in the survival, proliferation, and antibody production of B cell via the JAK-STAT signaling pathway and suppress pro-inflammatory cytokine secretion by blocking the NF-κB signaling pathway.

Applications

Cell Culture

Purification

>98% as determined by SDS-PAGE.

Endotoxin

<0.01 EU per 1 μg of the protein by the LAL method.

Bioactivity

Measure by its ability to induce proliferation in MC/9‐2 cells. The ED50 for this effect is <5 ng/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 7.4. 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 19.05 kDa. The protein migrates as 17-25 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.
