Storage Instruction:Store the kit at 4°C.
Description:
Interleukin 12 (IL-12), also known as natural killer cell stimulatory factor (NKSF) or cytotoxic lymphocyte maturation factor (CLMF), is a pleiotropic cytokine originally identified in the medium of cultured EBV-transformed RPMI-8866 cells . IL-12 is a 75 kDa glycoprotein heterodimer composed of two genetically unrelated subunits linked by a disulfide bond. 
Each subunit of IL-12 apparently arises from a single copy gene. The mRNA transcription of the subunits is closely coordinated, although an excess of the larger subunit has been shown to be produced by B cells in addition to active IL-12 . IL-12 activity cannot be demonstrated in the absence of either chain . As suggested by their names, p35 has a native molecular weight of 35 kDa while p40 has a native molecular weight of 40 kDa.
