A '''SNP''' stands for a '''S'''ingle '''N'''ucleotide '''P'''olymorphism. It is a very natural occurrence in the human genome. SNPs occur as sequence variations, fixed at different locations on the genome. SNPs can result in variations in the phenotype characteristics of the individual, such as hair type or their physical structure. They also affect the person's immunity and their reaction to certain medicines. These polymorphisms or genetic variations do more good than harm as they help in determining genetic linkage as well as drug efficacy and disease risk. SNPs are a collection of polymorphisms, and can occur as single nucleotide substitutions. Nucleotides are the essential building blocks of DNA and RNA. Changes or substitutions of these nucleotides have a direct effect on the individual. In general, SNPs are a major factor that contributes to biological diversity among organisms, and can be categorized into specific types, all with various effects on the human genome.

The results of our primer test were as follows: The non-disease primer was successful while the disease primer test did not yield any results. This is due to the single nucleotide polymorphism in the disease primers.

Procedure

Smart Phone Camera Settings

  • Type of Smartphone: Samsung S3
    • Flash: No Flash
    • ISO setting: 800
    • White Balance: Auto
    • Exposure: + 2.0
    • Saturation: No setting to affect Saturation
    • Contrast: Auto Contrast Off


Setup for Smart Phone Fluorimeter

Description of image


Calibration

Place the phone in the cradle with the camera lens lined up so that it shows a view of the slide from the side (edge-on). Once the camera is set up in the cradle and lined up with the side of the slide, adjust the slide so that the light illuminates the center of the drop and the drop focuses light on the other side of it. After adjusting the slide itself, change the distance of the smartphone from the fluorimeter in order to keep the drop in focus but keep the view close.

  • Distance between the smart phone cradle and drop = 5 cm


Solutions Used for Calibration

Concentration of 2X Calf Thymus DNA solution(micrograms/mL) Volume of the 2X DNA solution (μL) Volume of the SYBR GREEN I Dye Solution (μL) Final DNA concentration in SYBR Green I solution (μg/mL)
5 80 80 2.5

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. Find the rough side of the slide (making sure to only touch the slide while wearing gloves)
  2. Place the slide, with the rough side up, in the fluorimeter
  3. Locate the two clear circles in the middle of the slide and add 80 μL of SYBR Green I solution
  4. On the same circle with the SYBR Green I solution, place 80 μL of Sample/Calibration drops
  5. Adjust the slide so that the middle of the drop is illuminated by the light and the drop becomes focused on the side

SNP Information & Primer Design

Background: About the Disease SNP

A SNP stands for a Single Nucleotide Polymorphism. It is a very natural occurrence in the human genome. SNPs occur as sequence variations, fixed at different locations on the genome. SNPs can result in variations in the phenotype characteristics of the individual, such as hair type or their physical structure. They also affect the person's immunity and their reaction to certain medicines. These polymorphisms or genetic variations do more good than harm as they help in determining genetic linkage as well as drug efficacy and disease risk. SNPs are a collection of polymorphisms, and can occur as single nucleotide substitutions. Nucleotides are the essential building blocks of DNA and RNA. Changes or substitutions of these nucleotides have a direct effect on the individual. In general, SNPs are a major factor that contributes to biological diversity among organisms, and can be categorized into specific types, all with various effects on the human genome.


Primer Design and Testing

The results of our primer test were as follows: The non-disease primer was successful while the disease primer test did not yield any results. This is due to the single nucleotide polymorphism in the disease primers.
