||Interleukin 12 (IL-12, NK cell stimulatory factor, cytotoxic lymphocyte maturation factor) is a heterodimeric cytokine that is naturally produced by dendritic cells, macrophages and human B-lymphoblastoid cells (NC-37) in response to antigenic stimulation.
||Sf 21 Insect Cells.
||The predicted molecular weight of Recombinant Mouse IL-12 is Mr 54 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 70 kDa.
|State Of Matter:
||>97% by SDS Page and analyzed by silver stain.
||<1.0 EU/µg as determined by the LAL method.
|Storage And Stability:
||This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
