AllStars Mm/Rn Cell Death Control siRNA is a blend of highly potent siRNAs targeting ubiquitously expressed mouse/rat genes that are indispensable for cell survival. Knockdown of these genes induces a high degree of cell death, which is visible by light microscopy. AllStars Mm/Rn Cell Death Control siRNA facilitates siRNA transfection optimization and can be used routinely as a positive control. (For human cells, we recommend AllStars Hs Cell Death Control siRNA.)
