Update: First preliminary transformed algal colonies observed for pASapI-aaDa. Colonies survived reculturing on selective antibiotic media.
Update: First Preliminary transformed algal colonies observed for pASapI-CFP and pASapI-teal.
We initially experienced some challenges in our cloning experiments. We theorized that the issue was most likely due to secondary structures preventing our gene from being ligated properly. We overcame this problem by increasing the ligation time to 36 hours. The proinsulin bacterial work has also been delayed due to issues with getting the Western Blotting reagents shipped on time. Although the materials are now here, we had delayed some of the E. coli insulin work in order to complete more microalgae transformation work during the IndieBio EU three-month program. In addition, microalgae grow extremely slowly. We did not observe our first transformed colonies until 5 weeks after our first transformation experiments.
All molecular cloning results are verified using both PCR and sequencing.
