• Miniprepped directly transformed Gibson Assembly product for sequencing using the the Gibson nah1F and nah4R primers (each w/ 20 bp overhangs).
• Ran undigested miniprep with gel electrophoresis, looking for large bands corresponding to supercoiled DNA. The gel shows distinct bands for all three lanes. We interpreted this to mean that we got product. Submitted for sequencing.
