OverviewGet the critical information you need to move forward with confidence With SBI’s pPS-EF1α-GFP-RFP Positive Transduction Control Lentivector & Pre-packaged Virus, you can easily optimize transduction conditions for your specific cells by using GFP and/or RFP to image and measure transduction efficiencies. Available as ready-to-transduce, pre-packaged virus or ready-to-transfect lentivector, the pPS-EF1α-GFP-RFP Lentivector uses the moderate EF1α promoter to co-express copepod GFP and RFP. A T2A element mediates co-expression.Use the right promoter for your positive transduction controlIf the EF1α promoter does not provide the best expression levels for your positive control, you can choose from one of SBI’s other pPS-XXX-GFP-RFP Positive Transduction Control Lentivectors & Pre-packaged Viruses.PromoterExpression LevelApplicationCMVHighCommonly used in most cell lines (HeLa, HEK293, HT1080, etc.)MSCVHighHematopoietic and stem cellsEF1αMediumMost cell types including primary cells and stem cellsPGKMediumMost cell types including primary cells and stem cellsUbCLowMost cell types including primary cells and stem cellsSupporting DataSBI’s range of Positive Transduction Control Lentivectors & Pre-packaged VirusesFigure 1.
