Set up the phone camera to the three second timer and turn the flash off. (If the flash is not able to be disabled, skip this step) Place the phone in the holder and make sure the glass slide is level with the camera and in focus. Measure the distance between the phone and the fluorimeter (Make sure the camera is more than 4 cm away, in our experiment we used 7.8cm) Place 80 uL drops of SYBR Green I solution in the between the two circles that the blue light is illuminating. (Remember to use a new micropipette tip for each different solution and discarding the tips in the red disposable cup.) Place 80 uL drops of the sample solution onto the SYBR Green I drop that is already on the glass slide. Place the box over the fluorimeter with the opening on the side of the camera. Focus the image and click on the timer before covering the box with the lid OR cover the box as much as possible while clicking the shutter manually. Using the micropipette, remove all 160 uL solution from the slide and discard the solution into the red disposable cup. Move the slide so the blue light shines between two new white circles. Repeat this procedure for each sample three times. Put the glass slide in the sharps container once all the possible white circle have been used.

The drops were not green at all so it was negative. Patient 90113 : The values on this patient were -.0023, -.0024, and .0030 μg/mL. The drops were not green at all so it was also negative. Conclusions Patient 85470 : The results suggest that Patient 85470 is closer to the negative value. Patient 90113 : The results suggest that Patient 90113 is closer to the negative value. SNP Information & Primer Design Background: About the Disease SNP SNP is the abbreviation meaning Single Nucleotide Polymorphism and affect appearance, respond to drugs, and pre-disposition to diseases. In this lab, the particular SNP that is being analyzed is rs16991654, which is called Homo Sapiens (humans) in latin. On the National Center for Biotechnology (NCBI) page, numerous information on this SNP's can be found including the clinical significance, which is pathogenic or the disease linked to this SNP, which is Long QT syndrome (LQTS). The area of information that we focused on for the majority of the time is the gene sequence, which is KCNE2 where we analyzed the numerical position of the SNP (34370656) and had to not the non-disease forward primer, non-disease reverse primer, the disease forward primer, and the disease reverse primer. KCNE2 is gene coding which regulates numerous functions such as the neurotransmitter release, the heart rate, insulin secretion, neuronal excitability, and several others.

The image below shows the UCSC In-Silico PCR website results for the disease specific primers. The results show that there is "no matches."
