RNAi General Information
Media Recipes
Lab 4: Picking your gene to RNAi
Lab 5: Plasmid DNA isolation and transformation
Lab 6: Induction of RNAi plasmid and C. elegans feeding
Lab 7: Single Worm PCR and Agarose Gel Electrophoresis
Lab 8: PCR Reaction Cleanup and Sequencing

Schedule of Experiments

Lab # Dates Activity Outside lab time
4 9/29 - 10/5 Pick a single bacterial colony containing a plasmid for RNAi The night before next lab:

Set up an overnight culture of your colony

5 10/6 - 10/14 Plasmid DNA isolation

Transformation of the isolated plasmid into the HT115(DE) feeding strain

The next day:

Check control and transformation plates for growth - save your transformation plate
The night before next lab:
Set up an overnight culture of a single colony from your transformation

6 10/19 - 10/23 Induction of the bacteria to produce RNA

Seed plates and dry for bacterial feeding RNAi

3 days later:

Pick 3 gravid adult worms of N2, rrf-3 and rde-1 genotype to 2 RNAi plates for each genotype (6 plates total)
Incubate at 23°C until next class

7 10/26 - 10/30 Single worm PCR of N2 and RNAi treated worms

Agarose gel electrophorsis of PCR products

8 11/4 - 11/10 Clean up PCR reactions with Qiagen Min-Elute kit

Run sequencing reaction
Clean up sequencing reaction with columns

Analyze your sequencing data
