#Discard LiAc. Re-suspend in 160 µl of LiAc 100mM in the vortex (Total aprox. volume 500 µl).

July 12th

- We made a miniprep to purify the plasmids pG1 and pLZ.

Dani reading the protocol and Gabi moral support for the first miniprep!!

But before you start any procedure, you have to read the protocol!!!!

- Then we carried out a digestion and the following electrophoresis to verify whether we had the constructions in the plasmids and to evaluate their concentration.

Gabi and the high-tech device for run the gel!!

Gabi, Jose, Juan Angel and Dani's red hair doing the miniprep, almost done!!

First good result!! Here a picture of the electrophoresis. From left to right: Marker, pLZ and pG1.

We have the constructions and in a good concentration!

- We stored the non-digested plasmids in the refrigerator (we want to use it later on)

- We made (Jose made) a liquid culture of E. coli with the LEA gene, and puted it into the stove at 37ºC. Ale saying Jose what to do :D!!

  8. Add (important to follow the order)
    • 240 µl PEG 50% (p/v).
    • 36 µl LiAc 1 M.
    • 50 µl DMA carrier (2 mg/ml).
