NanoDrop
Purpose
The NanoDrop is used to quantify genetic material.
- Assemble cafeteria tray
- Kim Wipes
- 2µL pipette
- pipette tips
- gloves
- USB drive
- water and buffer tubes
- samples
- The NanoDrop is located in North Life Sciences, room 325A
Agarose Gel
Purpose
Agarose gels are used to verify the presence and estimate the size of DNA (both genomic and amplified). When loaded into a gel and subjected to an electric current, DNA fragments migrate to the positive terminal. Small DNA fragments migrate more rapidly than large ones. By running a commercially available ladder of fragments of known size, we can estimate the DNA fragment size in our sample of interest.
To visualize the DNA after electrophoresis, a dye called Gel Red is added during the agarose-making process. The dye binds to the DNA and flouresces when exposed to UV light.
Materials To Be Familiar With
Protocol
- Make gel using 1x TAE and agarose
- Use 1% for genomic DNA, 2% for amplified DNA
Gel Rig Size | 1x TAE (mL) | 1.5% agarose (g) | 2% agarose (g) | Gel Red (µL) | Sample volume (µL) | max voltage (V) |
