The first thing we had to do with the sample was to extract the DNA present in the water in a pure form for the PCR.
🔗
We did that with a Qiagen DNeasy PowerWater Kit.
🔗
As you would expect, this consists of a purification procedure with several steps.
🔗
In each step we take a physical or chemical action on the sample, which splits it into two parts: the one with the DNA and the one without.
🔗
We then take the part with the DNA, and throw away the one without the DNA.
🔗
The first steps are coarser, and finer and finer splits are done as we move forward.
