what does that mean? It stands for Polymerase Chain Reaction. This method measures how many DNA copies are present. This information is then used to determine if your DNA is contaminated or not.
In short, this is a simple way to check if you have been exposed to any harmful pathogens. In Cannabis this is extremely helpful when testing for mold. A quick PCR test can reveal mold contamination and give you insight into whether the contaminant has spread throughout the entire batch (or your entire operation) or just a single sample. PCR tests are a good way to know for sure whether you need to throw away your whole harvest or not. When I use my PCR machines in my lab at Green Coast Extractions, we run these tests on random samples from our clients. This is an easy way to give them peace of mind about their extractions.

PCR tests can take hours if not days to get results. These are some tips I have learned along the way about how long your results should take.
1) Always use fresh samples – old samples could be a little bit degraded or even dead. In these cases the PCR test may not work right.
2) If you don’t know what type of PCRs they sell at your local lab – always ask them. Some labs only offer conventional and other labs offer both conventional and real-time (QT).
3) If you are having trouble finding primers online, try contacting your local university or college. They might still have their own primers that they can share with you!
4) Try to start off with a low sample amount. If your sample is small enough, you can probably get a result faster than later on when you’re trying to amplify a much larger sample.
5) If you’re using a 96 well plate for your amplifications, make sure to fill out ALL wells. You want to make sure that each sample has ample room to wiggle around. Wie Lange Dauert Ein Pcr test
PCR tests are used to detect genetic material from pathogens that can harm your marijuana crops. This test can also confirm whether any of the marijuana’s DNA was transferred to other strains.
The first step in this test is to extract the DNA. To do this, take 1 gram of marijuana and grind it into a fine powder to get a good extraction. You might need to repeat this several times until enough DNA has been extracted. Then add alcohol (ethanol) and keep shaking it vigorously. Keep testing different ratios of ethanol to water to find the best ratio. The best ratio is 70% ethanol and 30% water. Once you have the perfect ratio, mix it together with the ground marijuana sample. Use the mixture to soak some paper towels and filter the solution through them. Place the paper towel containing the filtered solution into a sterile bottle and seal it tight. Leave the sealed bottle at room temperature for 24 hours. In the end, the DNA should remain inside the paper towels. Take out the paper towels and place them in a clean area away from direct sunlight. Let the DNA dry thoroughly for around 48-72 hours. After this time period, you can discard the paper towels and store the remaining DNA solution in a fridge until needed.
