Figure 4From: Multicistronic lentiviral vectors containing the FMDV 2A cleavage factor demonstrate robust expression of encoded genes at limiting MOI(A) EGFP expression (MFI) in K562 cells calculated per copy number from the flow cytometry data. Samples were selected among the cells having close to an average copy number of ~1. (a) eGFP, (c) MGMT-2A-eGFP, (d) MGMT-IRES-eGFP, (e) HOXB4-2A-MGMT-IRES-eGFP, (f) MGMT-2A-HOXB4-IRES-eGFP. (B). MGMT expression measured as biochemical activity in K562 cells following lentiviral transduction. Activity is presented as fmol/mg protein/transgene copy number. (b) MGMT, (c) MGMT-2A-eGFP, (d) MGMT-IRES-eGFP, (e) HOXB4-2A-MGMT-IRES-eGFP, (f) MGMT-2A-HOXB4-IRES-eGFP. All the values are expressed as mean ± SEM of 4 to 6 independent observations.Back to article page
