IL-12 Protein, Human (HEK293) is a HEK293 cell derived heterodimeric, pro-inflammatory cytokine.


Recombinant human IL-12 (hIL-12) is from the serum-free supernatants of stable IL-12-transduced HEK293 cells. Interleukin-12 is a heterodimeric, pro-inflammatory cytokine that is a key driver of cell-mediated immunity. Interleukin-12 (IL-12), previously known as natural killer cell stimulatory factor (NKSF) and cytotoxic lymphocyte maturation factor (CLMF), is a heterodimeric cytokine comprised of p40 and p35 subunits linked by an inter-subunit disulfide bridge. Among its many pleiotropic functions, IL-12 has been shown to induce: (i) IFNγ production; (ii) proliferation of activated T and NK cells; and (iii) TH1 differentiation. These functions are mediated by binding of intact IL-12 to its heterodimeric transmembrane receptor complex consisting of two chains, IL-12Rβ1 and IL-12Rβ2[1].

Biological Activity
The ED50 is <2 ng/mL as measured by NK cells, corresponding to a specific activity of >5 ×105 units/mg.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
