Recombinant mouse IL-12

Recombinant mouse interleukin-12 (with HSA)

Interleukin-12 (IL-12), also known as IL-12p70, cytotoxic lymphocyte maturation factor (CLMF) and natural killer cell stimulatory factor (NKSF), is primarily produced by dendritic cells and macrophages in response to bacterial pathogens [1,2]. It promotes Th1 responses and is a powerful inducer of interferongamma (IFN-γ). IL-12 is a heterodimeric 70 kDa cytokine composed of two subunits, p35 and p40.

Recombinant mouse IL-12 is intended for use in cell culture applications. It is produced in Chinese hamster ovary (CHO) cells transfected with a fusion gene encoding the p35 and p40 subunits linked by a decapeptide containing two elastin motifs. These transfected cells produce and secrete biologically active IL-12. Recombinant mouse IL-12 is purified by size-exclusion chromatography.

The activity of recombinant mouse IL-12 can be monitored in HEK-Blue™ IL-12 cells which express a STAT4-inducible SEAP reporter gene.
