By analyzing the results on the gel, our team concluded that a very long strand of DNA, likely the RCP, was produced. The gel exhibited a fluorescent band of DNA very close to the well, which indicates that a long strand of DNA, greater than 1 kB, was produced due to our reaction (see Fig. 1).

Rolling Circle Amplification(RCA) was successful with this part. The products of RCA are long DNA strands composed of repeating complementary sequences of the used padlock probe. Therefore, one way in which the success of RCA can be determined is by running the rolling circle products (RCP) on an agarose gel. Since a fluorescent band very close to the wells would indicate the presence of an extremely long DNA strand, our RCP was run on a gel. The result was a really long DNA strand close to the well.
By analyzing the results on the gel, our team concluded that a very long strand of DNA, likely the RCP, was produced. The gel exhibited a fluorescent band of DNA very close to the well, which indicates that a long strand of DNA, greater than 1 kB, was produced due to our reaction (see Fig. 1). As a result, we can infer that the RCA reaction allowed the creation of a really long DNA stand -- our RCP.
The RCP was also tested with the FAM and BHQ1 tagged linear DNA probes.
As shown by Figure 2, there is a statistically significant decrease in the fluorescent output of a triplicate with FAM Probe, BHQ Probe, and RCP as compared to a triplicate of just FAM tagged Probes. This confirms that we did produce our desired RCP in the RCA reaction and that this mechanism was an effective reporting method for our sensor.
Therefore, RCA created RCP that can be quantified by our chosen reporting mechanism.
