OUR TEAM Name: Tina Monteilh Name: Payson Wallach Name: Riley Baranek Name: Trisha Dasgupta Name: Robel Okbe LAB 5 WRITE-UP Procedure Smart Phone Camera Settings Type of Smartphone: Iphone 6 Flash: no flash used ISO setting:was not adjusted White Balance: was not adjusted Exposure: time: 1/15 of a second Saturation:was not adjusted Contrast: highest contrast available Calibration The camera (iPhone 6) was set up horizontally in front of the fluorimeter, and was placed in the cradle after the camera was adjusted according to the settings listed above. After adjustment, the image was checked to make sure that it was not blurry. The fluorimeter was raised up using one stack, in order to make sure the camera captured the best image possible, and the phone was placed 6.5 cm away from the fluorimeter. Distance between the smart phone cradle and drop = 6.5 cm Solutions Used for Calibration Initial 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 (μL/mL) 5 80 80 2.5 2 80 80 1 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 Using the mircopipette, place 80μL of the SYBR GREEN I onto the slide in between the first two rows, then add 80μL of of one of the concentrations of calf thymus from the table on top of the first drop of SYBR GREEN I so that one large drop is formed Make sure the drop is alighned so that the blue LED light is shining through the large drop Set the timer on the camera being used, and place the cover on the lightbox to make sure that the picture is taken with little to no light shining through Make sure to take 3 focused images of the drop Set the micropipette to 160μL and remove the large drop from the slide, before moving the slide to the next position Repeat steps 1-4 for the rest of the concentrations from the table Data Analysis Representative Images of Negative and Positive Samples Name: Green channel image of a negative sample. Name: Green channel image of a positive sample.

Patient 45821 : The ImageJ analysis had no light spot, and matched the calibration test with no DNA, making this patient negative Conclusions Patient 21533 : Since the ImageJ green analysis contained the light grey/white streak in the center, DNA was present, so it matched the positive control. Patient 45821 : There was no light spot on the Image J analysis for this patient, so it matched the negative control sample.
