Fig 1. Sub-cloning of HrasV12 and LTg into pMSCV plasmids.
(A) Genes of interest (i.e. HrasV12 or LTg) were inserted in between MSCV LTRs, and either GFP or RFP gene was used as a tracer gene. (B) Inserts cloned into pMSCV plasmids were confirmed by enzymatic digestions with either BamHI or EcoRI. M: DNA ladder, 1: pMSCV-GFP; 2: pMSCV-HrasV12-GFP; 3: pMSCV-GFPcut; 4: pMSCV-HrasV12-GFPcut; 5:pBABE-HrasV12cut (+ control); 6: pMSCV-RFP; 7: pMSCV-SV40 LTg-RFP; 8: pMSCV-RFPcut 9: pMSCV-SV40 LTg-RFPcut; 10: pBABE-SV40 LTgcut (+ control). White arrows indicate inserts. Sequences of insert were also verified by DNA sequencing.
