Transformingchemicallycompetentcells

MethodThaw TSS cells on ice.Add DNA, pipette gently to mix (1μl of prepped plasmid is more than enough).Note: If you are adding small volumes (~1μl), be careful to mix the culture well. Diluting the plasmid back into a larger volume can also help.Let sit for 30 minutes on ice.Note: If you are in a rush, you can shorten this incubation time to 5-10 min.Incubate cells for 30 seconds at 42oC.Note: According to the ......阅读全文
