Therefore, the crude extract of feces can be directly used as a reagent without purification.

It is easy to produce nonspecific reaction, which affects the accuracy of detection.

At present, it is all kit extraction.

They all use column centrifugation.

High purity.

You can't do it yourself.

Quite boring

It costs more than using a set of tools.

Virus genomic DNA extraction kit (centrifugal column)

This suit is only 2300 yuan.

You can use it 20 times.

And this: the common virus genome DNA extraction kit.

So my suggestion is to use the suite.

2300 yuan is Mao Mao's rain for molecular experiments.

And it's fast

Finish all the work in half an hour.
