Allele-Specific PCR (AS-PCR) is a convenient and reliable method for genotyping SNPs and mutations. Many variations of the original PCR method have been described, which include: In conventional PCR, nonspecific primer annealing can occur at low temperatures, and although the activity of the DNA polymerase is significantly compromised, extension can still occur. The use of thermostable DNA polymerases also allowed higher annealing temperatures, which improved the stringency of primer annealing.

Under stringent conditions, the mismatched primer will not initiate replication, whereas a matched primer will permit amplification. This generates a fluorescent signal in the annealing step that is proportional to the amount of PCR product. In addition, manual pipetting may be time consuming, tedious and can result in repetitive strain injury. As projects become larger and more laboratories adopt PCR-based tests, consistency, speed and performance become increasingly important. The first probe carries a donor dye at its 3' end, while the second carries an acceptor dye at its 5' end.

DNA polymerase is commercially available in both the native form and a cloned version that is expressed in non-thermophilic host bacteria. Traditional PCR is used extensively for clinical diagnostic applications; however, the technique suffers from lack of sensitivity. This generates a fluorescent signal in the annealing step that is proportional to the amount of PCR product.

Hot Start PCR can be achieved by simply withholding the polymerase until higher temperatures are attained. PCR kits are now available that enable the amplification of DNA >30 kb. Several strategies involve the addition of specific reagents to the reaction mix. This to optimize reverse transcription (RT) and fast PCR conditions for a four-target multiplex PCR assay. Despite the numerous variations on the basic theme of PCR, the reaction itself is composed of only a few components.
