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.

Results


We managed to see expressed GFP and RFP

Lab 115


Main purpose

Preparation for making competent cells based on the protocol.
