Transformation Protocol Using Heat Shock

1) Take chemically competent E. coli cells from –80°C freezer.

a. Use XL1-blue cells for all cloning and DNA-related tasks, BL21 cells for protein/peptide expression.

2) Turn on water bath or heat block to 42°C.

3) Competent cells should be in a 1.5 ml tube. For transforming a DNA construct, use 60 ul of competent cells. .

4) Keep tubes on ice.

5) Add DNA solution into the E.coli cell suspension, mix by flicking the tube. Incubate on ice for 15-30 min.

Note: 2 µL from a T4 DNA ligase reaction are usually sufficient

6) Put tubes into heat block at 42°C for 45 seconds.

7) Put tubes back on ice for 2 minutes to reduce damage to the E. coli cells.

8) Add 750 µL of LB or DYT (with no antibiotic!). Incubate tubes for 1 hour at 37°C and 750 rpm.

9) Spread 100 ul of the resulting culture on LB agar plates (with appropriate antibiotic added!).

Note: In case of "tricky" ligations which yield few colonies, spin down the cell suspension for 3 min at 6000 rcf (since you can't spread 800 µL), discard most of the supernatant, resuspend the bacterial pellet by pipetting and use this for spreading.

10) Grow overnight at 37 °C.

11) Pick colonies about 12-16 hours later.

Method:


Results:

check clones via colony PCR for correct insert
