Interleukin-12 subunit alpha (IL-12A, IL-12p35), an immune-suppressive cytokine, encodes a subunit of the cytokine IL-12 that acts on T and natural killer cells, and has a broad array of biological activities. IL-12A heterodimerizes with IL-12B to form the IL-12 cytokine or with EBI3/IL27B to form the IL-35 cytokine[1][2]. IL-12 Protein, Human (547a.a, HEK293, His) is produced in HEK293 cells with a C-Terminal His-tag . It consists of IL-12A (M1-S219) and IL-12B (M1-S328).
