What is, according to you, the best protocol for DNA extraction with magnetic beads technology, starting from 200 ul of whole blood?
May i know what kind of protocol you're referring to?
if u do it manually, lysing the sample and enzyme treatment to degrade protein, followed by binding of DNA with magnetic beads, incubate, washing with buffers and finally elute out the DNA.
these steps are commonly applied. hope this info is useful.
