Proper designs for the selection of PCR conditions with a PCR thermal cycler can play a critical role in the successful performance of the PCR reaction; if PCR conditions are not carefully selected, the end result may be an erosion or lack of useful product for a subsequent PCR application.
Therefore, choosing an appropriately selected and optimized design is an essential tool for determining the optimal PCR parameters for each experiment; the first steps for proper design for the selection of PCR conditions with a PCR thermal cycler is to select the appropriate components for the reaction.
The selection of thermocycler components is critical to obtain the best thermocycler conditions
The basic components of a basic PCR reaction include the PCR immunizers, the deoxyribonucleotides that are used as nitrogen suppliers for DNA synthesis, and the appropriate temperature for DNA extension during the reaction.
Once a mixture of components has been selected, it is recommended to create a PCA to conduct some rapid optimization tests, this will determine in real time pH, magnesium concentration, concentration of dNTPs and the optimal temperature for DNA synthesis within the PCR thermal cycler.
Objectives for optimizing dna amplification with the use of a thermal cycler in laboratory research
It is advisable to perform kinetic amplification to overcome PCR inhibition, this technique helps to ensure that dna products are amplified uniformly without interference during the reaction; the objective of this step is to optimize the incubation cycle time to obtain the highest quality of PCR products.
This will involve performing several tests at different time ranges to see what is the best incubation duration; likewise, the integrity of the amplified product must be verified, this can be done using gel electrophoresis for product visualization.
If researchers follow the proper design steps, the best results can be obtained for almost any PCR experiment
This technique helps to ensure that PCR-amplified products are of suitable quality for processing; the amount of product is also an important parameter to check, as it can be used to determine whether the PCR reaction design is effective.
In summary, the selection of suitable conditions for PCR with a PCR thermal cycler requires a carefully selected design to obtain the best results; this design starts with the selection of suitable components, a PCA for parameter adjustment, kinetic amplification to overcome PCR inhibition and verification of the amplified product.
