Recombinant Human Interleukin 2 (IL2) is a bioactive protein intended for use in cell culture applications. IL2 causes proliferation of T cells and is a central regulator of immune responses. The lyophilized, E. coli-expressed IL2 Recombinant Human is verified for activity through dose-dependent proliferation of mouse CTLL-2 cells.
• Highly Pure—minimizes interference from other proteins or contaminants • Active—get more results with less protein
High Purity To help verify that GIBCO™ Recombinant growth factors are of the highest quality, each protein is analyzed for purity, along with structural homogeneity, to help ensure a biologically active protein. The purity of each GIBCO™ recombinant growth factor is verified by SDS-PAGE to be over 95% pure and to have endotoxin levels below 0.1 ng/μg.
High Biological Activity All GIBCO™ Recombinant growth factors are verified for activity. Each lot has its own ED50 determined using an activity assay based on a specific function of the growth factor. The activity of our IL2 Recombinant Human growth factor is determined by the dose dependent proliferation of mouse CTLL-2 cells to have an ED50 range of 0.08–0.5 ng/mL. Optimal concentration for individual applications should be determined by a dose response assay.
