The genetic testing company 23andMe — which allows users to spit in a tube and send away the sample for a detailed DNA ...

To each tube add a volume of DNA corresponding to 3 μg (from Step 9). Bring the volume of the untreated control sample of DNA to 100 μl with water and store at −20 °C. Alternatively ...

These tubes are specifically engineered to minimise the adhesion of DNA to the tube walls, which is crucial in preserving the quantity and quality of DNA samples during various laboratory procedures.

Then, to perform PCR, the DNA template that contains the target is added to a tube that contains primers ... and decreases the temperature of the sample in automatic, programmed steps.
