Lab 301

Main purpose

We want to view our cells throught a fluorescent microscope, in order to see if they have expressed GFP and RPF.

Hopefully we will see GFP in the periplasm and RFP inside the cell.

Setup an overnight culture of the 2 successful transformants so we can both MidiPrep and isolate periplasmic proteins tomorrow.


We managed to see expressed GFP and RFP

Lab 115
