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 [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.
How the Fluorescence Technique Works [In your own words, a summary of the information from page 9 of the worksheet]
This method is used to examine and analyze the protiens, nucleic acids, ligands, and other interactions in order to study the protine orientations and actions. The different components in this technique, by micropipeting SYBR Green I and DNA onto a special glass plate and shining a blue light through it are the begining steps to analyzing the DNA stands in the drop.
