''[ | ''[Add a PHOTO for bonus points]'' The Single-Drop Fluorimeter is a box shaped device that shines a specific light spectrum to activate the florescent dye in the sample.The light is turned on by a switch on the side of the devices. The sample is placed on specially made glass slide that is perforated and hydro-phobic, the slide can then be placed into the Fluorimeter. <br> | ||

'''Conclusion'''<br> | |||
The objectives of the lab were met. The fluorimeter technique was mastered and calibrated. The formula to determine the magnitude of the light from a given concentration was found to be y = 4.0 x 10^6 (x) - 272558[2.7 x 10^6]. This can be used to find the concentration of DNA in an unknown sample by measuring the magnitude of light coming off the drop using the freehand tool mentioned above. | |||

LAB 2 WRITE-UPBackground InformationSYBR Green Dye SYBR Green I is a dye that is used as a nucleic acid stain in several fields such as biochemistry, and molecualr biology. SYBR Green I can be diluted and a small amount of it can go a long way. This dye was useful in this experiment because, when the drop of DNA is put on the glass slide there is a blue ray of light that is turned on, which then passes through the drop. The way that this compund, SYBR Green, works is by absorbing the blue light and emitting green light. When we taking a picture of the drop under dark conditions the green emmited light can be visible. This compound is part of the cyanine synthetic dye family, this words comes from the word "cyan" which is blue-green. That this why green light is emitted. Single-Drop Fluorimeter
