Characterization

We wanted to produce constructs without the elastin cross-linking domain. We removed this domain through Sap1 digestion of the DNA constructs and further transformed them into cells. We once again confirmed the success of the transformation with the digested constructs through gel electrophoresis and sequence verification. Although our sequence verifications were impressively similar to our desired constructs, it actually took 3 digestion attempts to fully digest the constructs to produce cells with constructs. While it is successful, the number of tries suggests that our Sap1 digestion with Golden Gate Assembly protocol could definitely be improved to increase efficiency.

We expect that digested constructs would be around 900 base pairs (bp). We used the gel to filter out picked colonies that did not contain the correct size of the constructs' DNA (such as S1.3). This was necessary, considering the inefficiency of the digestion protocol, so that we would only sequence colonies that were promising.
