PY Promoter - Preparation of electrocompetent cells of the conjugative strain

  • Now that we have PY1 promoter + RFP inserted in a plasmid with kanamicin resistance we are able to transform the conjugative strain. As we said before, this conjugative strain already has ampicilin resistance, that is why we inserted our construction in a plasmid with a different resistance.

  • Before transforming this strain we need to prepair electrocompetent cells. So today we inoculated a colony of this strain in liquid LB-AMP at 37ºC to prepare the competent cells tomorrow.

New strategy: pGEM

  • We did miniprep of 10 Adh1+Lysozyme colonies.

  • We digested the Adh1+Lysozyme/biofusion minipreps in order to connect it to the yeast expression vector (YEP358). We used the XbaI and PstI enzymes. 9 of 10 digestions worked! =) The expected fragment size is 2000bp.

  • We chose two fragments and purified them from the agarose gel. We ligated them to YEP358. We will transform it tomorrow.
