We will be testing a different combination of primers and template DNA to gain insight on why PCR of YF1/FixJ has consistently resulted in an incorrect amplicon of length ~1 kb (the correct amplicon should be around 1.8 kb). We will be using fresh template DNA from today (new minipreps of YF1/FixJ).
What we currently know:
●
The 1 kb band is not a result of reagent contamination given that PCRs of parts other than YF1/FixJ, using the same reagents (water, polymerase, buffer, etc.), have been successful and have not had the 1 kb band
●
The 1 kb band is not a result of contamination of the VR

Cut sites of enzymes that you select are highlighted to help guide your work.
(Enzymes with compatible ends turn the same color.)
Selecting cut sites and copying the sequence will also activate enzymes.
