Abstract
A protocol for transforming E. coli cells is shown.
Steps
Transformation
1.
Mix 50µL
of fresh competent cells with2µL
of genetic material (softly without pipetting) in a sterile 1.5 mL Eppendorf tube.
2.
Incubate On ice
for 0h 30m 0s
3.
Apply thermal shock in a water bath at 42°C
for 0h 0m 30s
4.
Immediately, put On ice
5.
Add250µL
of SOC medium (tempered at 37°C
).
6.
Incubate at 37°C
for1h 0m 0s
at 225rpm
.
7.
Disseminate 50µL
in a selective medium and incubate 1h 0m 0s
at 37°C
