- | * | + | * The plate of ''E. coli'' transformed with the pDLD+Biofusion had only two colonies. We did the colony PCR to find correct constructions of the pDLD and Lysozyme in Biofusion. We found two fragments corresponding to pDLD, but the negative control amplified the same fragment too! We decided to do miniprep of both colonies and re-confirm it by digestion. |
- | * We found one expected band of lysozyme. We did miniprep of this colony and chose an inespecific one as well. | + | * We found one expected band of lysozyme. We did miniprep of this colony and chose an inespecific one as well. |

- | * | + | * JENorf+pGEM grew!! Later that day we found out that we forgot to plate X-Gal =/ We did more plates, this time with X-Gal!! Waste of time!! =( |
- | * | + | * We digested the Lysozyme+Biofusion vector and pJEN1+Biofusion vector with ''Xba''I and ''Pst''I to recover the part fragment with one ''Not''I site. The Lysozyme digestion worked so we purified the correct fragment, ligated it in biofusion again in order to recover the second ''Not''I site. Unfortunately the pJEN1 digestion didn’t work. |

- | * | + | * An electrophoresis was made with the product of the digestion performed yesterday. Then, we purified the bands corresponding to the size of the pADH1 in the biofusion vector and the YFP part. |

+ | * So we made the ligation of the YFP part in the biofusion vector that contains the ADH1 promoter. Then we transformed this construction in ''E. coli'' that has grown O/N in the kanamicin media plate. | ||
