Goal

E coli DH5-alpha transformation with RFP from iGEM plate 4 - 2H (pSB1A3 backbone)

Procedure

  1. I took iGEM plate 4 - 2H (RFP, BBa_J04450 in PSB1A3 backbone) and resuspend it in 10 uL of distilled water.
  2. Used E coli competent cells from NEB 2 tubes c2987 (50uL) : 1 control (C) and one for transformation (T)
  3. Introduced 2 uL (200-300pg/ul) of my suspended plasmid solution in T.
  4. Waiting 30 min in ice
  5. Heat shock 30 sec 42°C
  6. Then 5min in ice
  7. Add 200uL SOC medium
  8. Recovery 2 hours then plate it on 3 different 100ug/mL Ampicillin LB
  9. Incubate 37°C till tomorrow

    10. Results

    The day after I had colonies growing, nothing on my control
  10. I took 2 different colonies and do a 8 hours culture in two different tubes T1 an T2 in LB + Amp 100ug/mL, in order to do a glycerol stock.
