SNPs, or single nucleotide polymorphisms, are an affliction on one's DNA. They are the most common source of genetic variation found among HomoSapiens, or the human population. <br>
Essentially a SNP takes one nucleotide and changes it into a different one. For example, if the nucleotide is supposed to be an A, an SNP will change the A into a T. <br>
By changing nucleotides, variations within humans arise, or the differences in humans' phenotypes (appearances).

Procedure

Smart Phone Camera Settings

  • Type of Smartphone: iPhone
    • Flash: Inactivated
    • ISO setting: N/A
    • White Balance: Auto
    • Exposure: N/A
    • Saturation: N/A
    • Contrast: N/A

Settings that are N/A:
Camera is sensitive enough to get a reasonable calibration with DNA concentration
Camera was focused when necessary


Calibration

  1. Turn on the camera on the smartphone and calibrate according to the settings above
  2. Place the smartphone in the cradle
  3. Place the cradle at a right angle to the slide
  4. Adjust the height of the fluorimeter using the plastic trays in order to take a picture of the drop sideways
  5. Adjust the distance between the cradle with the smartphone and the slide so that the cradle is at least 4 cm away from the slide
  6. Record the distance between the cradle and the slide with a ruler
  • Distance between the smart phone cradle and drop = 8cm


Solutions Used for Calibration


  • Water at pH = 8
  • SYBR green I dye solution
  • DNA solution

Placing Samples onto the Fluorimeter

  1. Use the pipettor to place a drop of the SYBR green I dye solution (80 microliters) in the middle of the first two rows of the slide
  2. Use the pipettor to add a drop of the water blank solution (80 microliters)
  3. Adjust the slide so that the drop focuses the blue LED light to the middle of the black fiber optic fitting on the other side of the drop
  4. Cover the fluorimeter and camera with the light box so that all stray light is removed
  5. Take three pictures and make sure the drop is focused
  6. Remove the box
  7. Use the pipettor to remove the drop from the slide (160 microliters)
  8. Move the slide to the next position
  9. Repeat steps 1-8 for the patients and the DNA solution

PCR Results Summary

  • Our positive control PCR result was 0.05596862783 μg/mL
  • Our negative control PCR result was 0.02701367497 μg/mL

Observed results

  • Patient 11316 : There is a notable amount of the SYBR green I dye solution in the drop.
 0.01599345468 μg/mL
  • Patient 25353 : Compared to patient 11316, the amount of SYBR green I dye solution in the drop is insignificant. There is still a significant amount present, however, patient 11316 shows more of the dye.
 0.02401010622 μg/mL

Conclusions

  • Patient 11316 : It was concluded that the patient did not contract the disease because the PCR concentration is close to the the negative control PCR result.
  • Patient 25353 : It was concluded that the patient did not contract the disease because the amount of dye present in the drop is less than the amount of dye present in the drop for patient 11316. Both the PCR concentrations in the drops are extremely close to the negative control value amount, however patient 25353 shows a lesser amount (closer to the negative control)
