Calibration
The Camera was set up such that we could get the clearest image with maximum LED light absorption. A light box was placed over the fluorimeter to darken the area. The Smart phone was aligned with the slide to get a sideways picture of the DNA sample. This creates the ideal angle to observe any fluorescent light after the picture is taken. The camera phone is calibrated to view the fluorescent light with little interference from contrast and recording the most light- done by setting the exposure high. The saturation is set to low so that color is not rendered in the photo. the ISO is set to

Placing Samples onto the Fluorimeter

  • 1.) With the Camera set in place we prepared the slide with SYBR Green I, a constant throughout the experiment
  • 2.) 80 μL of 5μg/mL of calf thymus concentration DNA samples were then added to the slide
  • 3.) To take 3 pictures in the the dark with as much of the blue LED light as possible, we used a timer on the camera, set to 3 seconds.
  • 4.) The slide, now containing SYBER Green I and Calf Thymus DNA was then aligned in the cradle such that the light was shining into the DNA.
  • 5.) With the Camera phone, we captured 3 images of the DNA and removed the light box.
  • 6.) That sample was then disposed of with a micropipette
  • 7.) Repeat with 80μL Green SABR I and 80μL of each Calf Thymus Concentration given by the first column in the table above
