- Culture overnight of JM101 and JM109 strains.
- Dilution 1:100 in 30ml of sterile LB media. Incubate for 2.5-3hrs at 37°C.
- Thaw on ice for for 10 minutes. transfer to 12 vials.
- Centrifugate for 7min at 4°C at 3500rpm. Eliminate supernatant and decant. fill the vials with the culture and centrifugate again. Repeat ≈ 3 times.
- Resuspend the pellet in 1ml of sterile cold 10mM MgCl2in each vial. Add 500µl of 10mM MgCl2 to eeach vial.
- Centrifugate at 3500 rpm for 7min at 40°C.
- Eliminate the supernatant and resuspend in 100µl of 50mM CaCl2, Glycerol at 20%. Add 100µl of 50mM CaCl2, Glycerol at 20%. Incubate 1hr at 4°C.
- Transfer to 0.5ml eppendorf tubes and freeze.
- JM101: In blue the corresponding vials to this Escherichia coli strain.
