Ligations 07/22
- We ligated P1A (vector) to CDF. We used three different ratios of vector to insert for the ligation: 2/6, 1/5, 1/7.
- Attempted to ligate p40 cut with SP (w/ RBS) to mtrB cut with XP. Thus far, the ligation has not worked.
Recombination Update 07/22
- Thus far, none of the attempts to extract flanking regions from the genomic DNA have worked. We are troubleshooting this now and will run positive controls with known DNA samples to check the efficiency of our Phusion Polimerase.
