The STEMCCA Constitutive Polycistronic (OKSM) Lentivirus Kit contains high titer polycistronic (OKSM) lentivirus and Polybrene transfection reagent that have been validated for the generation of mouse and human induced pluripotent stem cells from mouse embryonic fibroblasts (MEFs) and human foreskin fibroblasts (HFFs), respectively. The STEMCCA vector is comprised of the transcription factors Oct-4, Klf4, SOX-2, and c-Myc (OKSM), separated by the self-cleaving 2A peptide and IRES sequences (Sommer CA, 2009). The use of a single polycistronic lentiviral vector significantly improves reprogramming efficiencies and reduces the number of viral integrations.

Tested to confirm the generation of iPS cells from p3 mouse embryonic fibroblasts and p6 human foreskin fibroblasts. Other cell types have not been tested and thus similar results can not be guaranteed.
