The polymerase chain reaction (PCR) is one of the most well-known methods in life science laboratories.
PCR plates are made of first-class plastic for excellent handling and analysis of collected samples or results.
They have thin, uniform walls that provide precise heat transfer.
In preparation for real-time application, tiny fractions of DNA or RNA are isolated and stored in PCR plates.
PCR plates are very efficient at heat sealing and also restrict the flow of heat.
However, because PCR plates are efficient and reliable, they are prone to errors and inaccuracies when processing samples.
So if you are interested in getting good quality PCR plates. It is best to contact a reliable PCR plate manufacturer. With this, you can be sure to get the best price.
Below are some precautions to avoid contamination of reagents or samples and to prevent inaccurate results.
Disinfect the environment
Incorrect positive or negative results due to the presence of impurities can make you doubt the results.
Impurities and contaminants come in various forms, such as unrelated DNA or chemical additives, that ultimately reduce the efficiency and effectiveness of the reaction.
There are many ways to greatly reduce the contamination rate of PCR plates.
Using sterilized filter tips is another useful way to prevent impurities from entering the sample through the pipette.
A completely clean set of equipment, including pipettes and racks, is provided specifically for PCR use. This will guarantee negligible transfer of impurities or contaminants around the laboratory.
Use bleach, ethanol on pipettes, racks, and benches to wipe off contamination.
Allocate reserved space for all PCR reactions to further reduce particle contamination.
Use clean gloves at every step and change them frequently.

Check the concentration and purity of the template.
The cleanliness of benches and equipment used to analyze samples using PCR should be maintained. It is critical to verify the purity of samples prior to analysis and processing.
Typically, the analyzer takes into account the concentration and purity level of the DNA sample.
The absorbance ratio of 260nm/280nm should not be less than 1.8. The impurities were then identified using wavelengths between 230nm and 320nm.
In one example, chaotropic salts and other organic compounds were detected at an absorbance of 230 nm. Simultaneously detect and verify turbidity in DNA samples at absorbance at 320nm.
Avoid overloading PCR plates and products
Although it is desirable to run multiple products at the same time, it can lead to cross-contamination of PCR plates.
Overloading PCR plates with different products is wasteful and makes it difficult to identify samples.
Keep records of aliquots of PCR reagents
Continuous freeze/thaw cycles and frequent use of aliquots may damage PCR reagents, enzymes, and DNTPs through recrystallization.
Always strive to monitor the rate of aliquots used when preparing samples for analysis.
The preferred LIMS is more suitable for controlling stocks and quantities of reagents and samples to be frozen or thawed.
Choose the optimum annealing temperature.
Choosing and using the wrong annealing temperature is another way PCR results contain errors.
Sometimes the response doesn't go as planned. The annealing temperature needs to be lowered to promote a successful reaction.
However, lowering the temperature increases the chance of false positives and primer-dimers.
When using PCR plates, it is important to confirm the analysis of the melting curve as it is a good indicator for choosing the correct annealing temperature.
Primer design software aids design, providing the correct annealing temperature, directly reducing errors in PCR plates.
