Set up the Flourimeter. Place slide in the flourimeter with the smooth side down and the rough side up. Place one, 80 micro-mL drop of SYBR Green on the slide, between two of the dots on the slide. Place one, 80 micro-mL drop of a calf thalmus solution on the slide so it combines with the SYBR Green. Adjust the slide so the light shines through the drops. Adjust and record camera distance. Start camera video and close the fluorimeter. Wait a few seconds and remove camera, take screenshots on the video at different times and send them to be analyzed. Discard the droplets and slide. Repeat.

None of them glowed green. All of this patients concentration results were above the negative control. Patient 54283 : All images taken of patient two' DNA samples appeared to be negative as well as none of them glowed green like the positive sample did. However, not all of the values of concentration found for patient two were above the negative control. Conclusions Patient 81166 : Based on the images alone, this patient tested negative.The data calculated shows all concentrations to be above both the negative and positive controls which suggests the sample to be negative as the negative concentration was found to be higher than the positive. The final conclusion is this patient is negative. Patient 54283 : Based on the images alone, this patient tested negative. The data calculated shows two of the three concentrations to be above both the negative and positive control and one below. This still impliess that this patient is negative. Examining only the data collected, it is hard to determine a result as all the data found using Image J is relatively similar. The positive and negative control concentrations were very near to each other with the negative control having a higher concentration than the positive control. The data collected for the patients ranged both above and below the controls.This suggests an error was made and further testing would be needed to get a definitive result. SNP Information & Primer Design Background: About the Disease SNP A nucleotide is a subunit of a nucleic acid and a polymorphism is when two or more clearly different phenotypes exist within the same population. Therefore, a SNP, or single nucleotide polymorphism, is simply a DNA sequence variation where a single nucleotide is different when compared to others of the population. The variation rs1699154 is found in Homo Sapiens a.k.a humans. It is located on the chromosome 21:34370656. This SNP is pathogenic and associated with the KCNE2 gene-- which stands for potassium voltage-gated channel-- and the cardiac disease Long QT Syndrome. Primer Design and Testing The KCNE2 gene stands for potassium voltage-gated channel Isk-related family, member 2. The non-disease allele is TTC but the disease-associated allele contains the sequence is CTC. The numerical location of this SNP is 34370656. The numerical position needed for the non-disease reverse primer is exactly 200 bases to the right of the SNP at 34370856. the non-disease forward primer is 5'-catggtgatgattggaatgt, the reverse primer sequence is 5'-cccttatcagggggacattt. Similarly, the disease forward primer is 5'-catggtgatgattggaatgc and the disease reverse primer is cccttatcagggggacattt. Error creating thumbnail: File missing Error creating thumbnail: File missing
