Make transfection reagent (TR,lot 20111107) to freeze-thaw each 2 weeks. lot 20111107

3 ul TR + 50ul DMEM without serum---->Mix A

1 ug DNA(pCMV-EGFP) + 50ul DMEM without serum---->Mix B

Mix A + Mix B, incubate 20min at room temperature

Add 100 ul mixture to transfect 293T cells in 12 well-plate.


0 is control. (2011.11.7)

2 is TR frozen 2 weeks. (2011.11.21)

48 hours after transfection
