Obtain a micropipet that is able to transport 80 microliters, fluorimeter, glass slides, camera, stand for camera, and box to cover the system. Set up the system so that the camera will be able to take pictures of the side view of the sample. Place 80 microliters of the SYBER green on the rough side of the glass slide between the two dots. Then place 80 microliters of the sample being used on the orb of SYBER green. Carefully place the glass slide in the fluorimeter so the beam of light is passing through the orb, then cover the system with the box no light will be able to penetrate. Set up camera up to timer of 5 seconds, press the take picture button and close the open end of the box. Repeat steps 5 through 6 for multiple samples being tested.

PCR Results Summary

• Our positive control PCR result was _3.15___ μg/mL
• Our negative control PCR result was __-0.15__ μg/mL

Observed results

• Patient 76447 : A value of 2.19μg/mL was obtained for our final product. It was observed to be a green when we placed the green dye in it.
• Patient 58040 : A value of 3.55μg/mL was obtained for our final product. It was observed to be a bright green when we placed the green dye into it.

Conclusions

• Patient 76447 : The value for this patient is higher than the negative control, but lower than the positive control. This means that it has a concentration of DNA, but that concentration is still lower than our controls concentration. This is why the color is not as bright.
• Patient 58040 : The value for this patient is higher than both the negative and the positive control. This shows that it has a higher concentration of DNA than the positive control. This explains the bright green color of the droplet.

SNP Information & Primer Design

Background: About the Disease SNP

Single Nucleotide Polymorphisms which are frequently called snips, are the most commonly attributed genetic variation among humans. SNP's occur normall throughout a humans DNA replacing single nucleotides- the building block of DNA. These snips occur once per 300 nucleotides roughly and can act as bio markers for scientists. These snips are flags for scientits to locate where or which gene is causing a certain disease. SNP's can be used to track inheritance of diseases gnes within blood.

Primer Design and Testing

The reulsts of our primer test were conclusive. The non-disease primers or the unaltered section, the test proved to be successful of a match. When we tested the disease primer the test was a fail which means that the two sections where not a match. This is because of the single replacement of a nucleotide in the diseased primer.
