- 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. |
