 +
We transformed L 139, L140, L141 and L142 following the [[Team:Paris/Notebook/Protocols#Transformation|standard protocol using Invitrogen's TOP 10 chemically competent cells]]. The positive control is a transformation with pUC19 and the negative control has no plasmid.

Assay to purify a PCR product using the Qiaquick Gel Extraction kit

  • sample used: yesterday PCR product of L130.8 (~40 µL)
  • protocol used: Qiagen PCR purification kit
  • use of buffer QG (Gel Extraction kit) instead of buffer PBI (PCR purification kit)
  • elution in 30 µL of buffer EB
  • 30 µL of purified product + 12 µL of loading blue
  • electrophoresis, 10 µL loaded

=> see Gel 1, well n° 8

==> results: PCR products can be purified using the Qiaquick Gel Extraction kit. We just have to replace the buffer PBI by the buffer QG!

PCR screening

Electrophoresis Setting

4 more transformants of L130 (pFlhB into J61002) are screened by PCR.

  • PCR screening programm; elogation time: 1 min 30
  • template: colonies from the transformation plate
  • positive control: S142 (J61002)
  • negative control: no template
  • primers: O18 and O19

Transformation of the ligation we did yesterday

We transformed L 139, L140, L141 and L142 following the standard protocol using Invitrogen's TOP 10 chemically competent cells. The positive control is a transformation with pUC19 and the negative control has no plasmid.
