Nt1310 Unit 6 Lab
1.) Test for viscosity: Since DNA molecules are long strands that anneal to each other, they can be very viscous in liquid if they're at a high enough concentration. If I notice the sample sticking together while pipetting it, I'll often know that I have a lot of DNA in the sample.
2.) Precipitate the DNA: It is possible to evaporate all the water in the tube and leave behind only DNA. It will appear as a tiny white spec in the bottom of the tube. However, this isn't very informative as you can't easily tell how much DNA you have and it takes a while.
3.) Use an instrument to determine DNA quantity: These instruments are standard in most molecular biology labs these days. The two most common ones I see these days are the Nanodrop and the
