- Molecule
- IL12B/IL-12 p40/NKSF2
- Background
- Interleukin 12 (IL-12) is a pro-inflammatory cytokine with a molecular weight of 70 kDa composed of two subunits, IL-12p35 (35 kDa) and IL-12p40 (40 kDa). IL-12p40 is induced in excess over the other subunits of IL-12 and IL-23 and can exist in a monomeric or homodimer form.

- Shipping
- The product is shipped on dry ice/polar packs.
Upon receipt, store it immediately at the temperature listed below.
- Storage
- Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt.
Reconstituted protein solution can be stored at 2-8°C for 2-7 days.
Aliquots of reconstituted samples are stable at ≤ -20°C for 3-6 months.
Please minimize freeze-thaw cycles and use a manual defrost freezer.
- Reconstitution
- Reconstitute the lyophilized protein in sterile water at a concentration of greater 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.
