1 80 80 0.5
0.5 80 80 0.25
0.25 80 80 0.125
0 80 80 0

Placing Samples onto the Fluorimeter

  1. Dispense 80μL of SYBR GREEN onto the first two middle dots of the glass tray, make sure the rough end is pointed up.
  2. Dispense 80μL of the Dalf Thymus DNA solution onto the SYBR GREEN drop.
  3. Close the system that the tray is on so that little to no light can penetrate the drop.
  4. Turn on the light and take three bursts of pictures of the drop

PCR Results Summary

  • Our positive control PCR result was 80 μg/mL
  • Our negative control PCR result was 80 μg/mL

Observed results

  • Patient 59797 : The solution was clear, or had a hue of blue due to the flourescent light. This was observed in the three duplicates of the first patient's DNA.
  • Patient 79049: The solution was clear, or had a hue of blue due to the flourescent light on 2 of the three duplicates. However for the 2nd dupliate, 2-2, the drop was a green color.


  • Patient 59797 : The patient tested negative for diabetes.
  • Patient 79049 : The patient testes positive for diabetes.

SNP Information & Primer Design

Background: About the Disease SNP The SNP was a Pathogenic disease that has an association with coronary heart disease. The variation is found in humans and affects the NHGRI, GWAS, and PheGenl genes.

Primer Design and Testing

For the non-disease DNA code, the result was matched 220bp because there was no mutation on the 3 prime end of the code. For the disease DNA code, the result was 'no matches' because there was a mutation at the 3 prime end where the A nucleotide aligned to a G nucleotide. Thus causing the mutation and the 'no matches'.
