• Background

  • 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), and IL-12p35 as a p35-p35 homodimer with 57 kDa molecular weight and a p35 monomer of 27 kDa molecular weight. The p35 molecule is unique to IL-12, while p40 is shared by both IL-12 and IL-23. IL-12 promotes Th1 T cell responses, while IL-23 promotes Th17 T cell responses.

• Instruction

  • Reconstitution

    It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration of 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

    Shipping

    The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

  • Stability & Storage

    This product is stable after storage at:

    • -20°C for 12 months in lyophilized state from date of receipt.
    • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

    Avoid repeated freeze/thaw cycles.
