fluorescence polarization assay
Friday 25 November 2011
Currently, the most used methods for genotyping of SNPs are costly and time consuming. It is necessary to develop a method that is more accurate, cost-effective, and simple.
An improved fluorescence polarization assay based on asymmetric polymerase chain reaction hybridization for screening SNPs has been developed.
Studies show the accuracy, simplicity, and cost-effectiveness of the fluorescence polarization assay in the detection of SNPs.
In a study, the fluorescence polarization assay is more accurate for the heterozygous sample than is the sequence assay. The minimum detection level established with the fluorescence polarization assay is 2.5 genome copies per reaction and no cross-reaction is observed. (20736746)
