Testing DH5α competent cells by transformation

This was performed according to tranformation protocol From NEB 5-alpha competent E.coli (High Efficiency) NEW ENGLAND BioLabs.

I transformed both my own cells from yesterday and also the kit's competent cells. Each one had a two serial 10-fold dilution.


Preparation LB agar plates with ampicillin resistance

LB agar:

  • 25 g LB
  • 15 g bactoagar
  • Fill up to 1 L with distilled water
  1. Autoclave for 120°C, 20 min
  2. Cool down
  3. Add 200 mg ampiciliin in 1,8 ml water
  4. Pour out on plates

  • up to 1L ddH2O
  • Autoclave 120 °C 20 min
  • Cool down
  • Add 200 mg Amp in 1,8 ml H2O
  • For 1L of LB add 1 ml of 100 mg/ml
  • Pour on plates

PCR

PCR of SOD and yCCS to add prefix/suffix
