This part was experimented with as a part of the composite part, the hsa-mir-133a-3p RCA Padlock Probe (<partinfo>BBa_K4245204</partinfo>).
+
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.

In order to quantify the relationship between miRNA concentration and fluorescence, we further characterized these parts with varying linear probe complement concentrations. There is a negative logarithmic correlation between the complement concentrations and the relative fluorescence units (RFU) (see Fig. 12). Moreover, the data shown above closely parallels the predictive ordinary differential equation (ODE) model (see Fig. 13) correlating complement concentration to RFU (see Modeling).Therefore, the overall data collected depicts an accurate relationship between the miRNA concentration and RFU, further validating that RCA coupled with linear probes are an effective and efficient means of quantifying miRNA concentrations.

Applications of BBa_K4245204

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.

Figure 1. Image of gel ran with miRNA 133a RCP product.RCP is visible in wells 7 and 8.


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.


Linear Probes with RCP
We use linear probes as a means to quantify and report the miRNAs that we sensed through rolling circle amplification (RCA) reactions. To go beyond verifying that linear probes are efficient means to do the aforementioned tasks through testing with complement of the linear probes, we wanted to confirm that they are able to quantify the miRNAs experimentally (see RCA Protocols)

Figure 2. Fluorescent Read of Rolling Circle Product for miRNA-133-3p and miRNA-1-3p

As shown by Figure 2, there is 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 for our miRNA-1-3p and miRNA-133a-3p sensors 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.
