Polymerase chain reaction (PCR) is a widely used technique in molecular biology for the amplification of DNA fragments. PCR involves several steps, including denaturation, annealing, and extension. The success of this technique depends largely on the quality of the PCR plates and tubes used. There are many factors to consider when selecting the appropriate PCR plates and tubes for your application.Here are some key factors to consider:
1. Capacity PCR plates and tubes come in different sizes and capacities. The choice of size and capacity depends largely on the amount of DNA that needs to be amplified in a single reaction. For example, if you need to amplify a small amount of DNA, you can choose a small tube. If a large amount of DNA needs to be amplified, a plate with a larger capacity can be selected.
2. Material PCR plates and tubes can be made of different materials such as polypropylene, polycarbonate or acrylic. Polypropylene is the most commonly used material due to its chemical and heat resistance. It is also less expensive compared to other materials. Polycarbonates and acrylics are more expensive, but have better optical clarity and are ideal for real-time PCR.
3. Thermal conductivity PCR involves multiple thermal cycles, requiring rapid heating and cooling of the reaction mixture. Therefore, PCR plates and tubes must have good thermal conductivity to ensure uniform heating and cooling of the reaction mixture. Plates with thin walls and flat surfaces are ideal for maximizing heat transfer.
4. Compatibility PCR plates and tubes should be compatible with the thermal cycler you are using. Plates and tubes must be able to withstand the high temperatures required for amplification of DNA fragments. Always consult the thermal cycler manufacturer for recommended plates and tubes.
5. Seal A tight seal is critical to prevent contamination of the reaction mixture. PCR plates and tubes can be sealed using different methods such as heat seals, adhesive films or lids. Heat sealing is the safest method and provides a strong barrier against contamination.
6. Sterilization PCR plates and tubes must be free of any contaminants that may interfere with the reaction. Therefore, they must be sterilized before use. It is important to choose plates and tubes that are easy to sterilize and resistant to chemical and heat sterilization methods.
In summary, choosing the right PCR plate and tubes is critical for successful DNA amplification. The choice depends largely on the type of application, the amount of DNA amplified, and compatibility with thermal cyclers.
