Hello all!
I am currently trying to clone a 120bp fragment. However, I am getting a low yield. I am using 2ul of 50ng DNA for the PCR reaction. I have also tried a gradient and I am using the best temperature I found for this primers. I am also using DMSO and Phire Polymerase.
In addition, my primers are 22bp long plus 5bp of restriction enzymes, and three nucleotides to enhance restriction activity.
Should I just order new primers?, However, I don't have that much room to vary them as I am amplifying signal peptides, should I use this resulting reaction as a template as I am also getting some genomic DNA amplification?
THANKS!
