Karina's Notebook
Need to redesign oligos! It seems that there is a sequence of 16 bp of the "rev-comp scar + scar" that is forming homodimers and selfdimers. 16 bp is significant since our annealing region for the primers is ~20 bp, thus a lot of unwanted byproduct is forming in the PCR stitching reaction. Instead of stitching our parts, we will design our oligos so that they are each the full length of the strand and anneal the two strands together. We will also design our oligos so that they anneal with the XbaI and PstI overhangs, enabling us to skip the restriction digest step.
To redesign!
