As you can see from our gel image, our product is present in both reactions (TAQ and TAQ+Phusion).

-
After purifying our products we find out that the concentration of DNA that we obtained is too low (about 5ng/ul) maybe for an experimental error in setting the PCR program. For this reason, our team is going to redo the PCR reaction again.
