pMSCV-Puro plasmids (where MSCV is mouse stem cell virus) containing full-length humanKRASgenes (WT, G12D) were constructed using standard molecule biology techniques by inserting theKRASgene fragment between the BamHI and XhoI sites. Transfection-grade plasmids were prepared using ZymoPure II Plasm...
