Cat#:RP-4021H;Product Name:Recombinant Human IL12 Protein;Synonym:NKSF, CTL maturation factor (TCMF), Cytotoxic lymphocyte maturation factor (CLMF), TSF, Edodekin-alpha, IL-12.;Description:Interleukin-12 Protein produced in HEK cells is a glycosylated heterodimer, having a total molecular weight of 57kDa. The IL12 is purified by proprietary chromatographic techniques.;Source:HEK.;Purity:Greater than 95% as obsereved by SDS-PAGE.;Bioactivity:The specific activity was determined by the dose-dependent release of IFN-gamma from the human NK92 cell line in presence of 20ng/mL rIL-2. The EC50 is 0.5ng/ml.;Formulation:IL12 was lyophilized from a 0.2µm filtered solution containing 1xPBS.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized IL12 in sterile PBS containing 0.1% endotoxin-free recombinant HSA.;Storage:Lyophilized?IL-12 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL12 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
