  • Well 1 : 6µL DNA Ladder
  • Well 2 : 5µL BBa_K1155000 digested by SpeI/PstI +1µl of 6X loading dye
  • Gel : 0.8%

Expected sizes :

  • Pndh* : 111bp
  • pSB1C3 : 2070bp

We can't see any band for BBa_K1155000 digestion. The digestion failed because we used the wrong enzymes. We will do it again with the good ones.

It's impossible to read the first gel. We do it again. In the second gel, we obtain FNR Part I and FNR Part II fragments at the right size. We can purify it. We also obtain BphR2 Part I frangment at the right size but it was mix with other DNA frangments. We will try to make a gel purification of it.

Even if the two lightest stripes are overlapping, aims to do a second gel purification with these two stripes, we did the gel purification . After argumentation, we decided to do the PCR of BphR2 Part I again thanks to new PCR program and new quantities.
