Lab Work

B - Construction of the fusion protein (color)

PCR clean-up of colonies containing pGEMTeasy+chromoprotein

by Sean

Three colonies were selected from the gel prepared earlier by Laetitia, namely #3,#4, and #6. The three gel samples underwent PCR clean-up.

Gel electrophoresis of PCR clean-up results containing pGEMTeasy+chromoprotein

by Sean

PCR clean-up was performed ealier today. 1µl of each result was used for the electrophoresis. Nothing appeared under UV.

Transformation of odor free E. coli with plasmids coding Fluo Protein

by Terry

Our fusion protein was not expressed in pGEMTeasy (no color in the culture), so, if our system do not work at all, I'm preparing FP (Fluorescent Protein) for our lemon.

6 plamids coding FP have been transformed in Odor Free :

• pEYFP
• pGFP
• pESFP
• pRFP+
• pCFP+
• pYFP+

D - lemon scent
