IL-12 protein forms a heterodimer with IL23A to produce the cytokine IL-23, which is critical in innate and adaptive immunity. IL-23 works synergistically with IL-17 to promote the acute response of peripheral tissues to infection. IL-12 Protein, Cynomolgus (HEK293, His) is a recombinant protein dimer complex containing cynomolgus-derived IL-12 protein, expressed by HEK293 , with C-His labeled tag. IL-12 Protein, Cynomolgus (HEK293, His), has molecular weight of 45-48 kDa (IL-12B) & 38-44 kDa (IL-12A), respectively.
