Week 5: July 24 - July 30
Objective: Troubleshooting issues with GFP and RFP transformation
- The plates did not come out the way we wanted it to be. So therefore an investigation of what we did for the past week was listed
- Day 1: Transforming E.coli - positive control worked therefore the transformation should work
- Day 2: Colony selection and Colony PCR - might have selected wrong colonies to work with
- Day 3: PCR clean ups - found foreign DNA inside samples after the cleanup was done
- Day4: Transformation using legations - possibly wrong backbone/ not enough backbone or possible error with ligation
- Used old plates and re selected colonies for Colony PCR
Results: The transformation from yesterday did not turn out the way it's suppose to be. Therefore we came up possible errors that may occurred during different days. As a result we re conducted the experiment from Colony selection hoping that it would work this time.
Objective: Continuing to troubleshoot
- PCR cleanup the RFP and GFP
- Made 0.7% agarose gel for viewing the base pairs of the plasmid mini preps

- Transformation of the LEAs came out great but the colonies were green
- Colony PCR was done and a gel was ran
- The gel came out fine but there were bands at 3000bp resulting in inconclusive results
Results: The results of the transformed plates fluorescing green indicates the misusage of the promoter, RBS, and backbone part.
