There are several different chemistries that can perform SNP Genotyping amongst which are KASPar®, Taqman®, and Invader®. These chemistries rely on the detection of multiple fluorophores for each sample and when screening thousands of samples an instrument is needed that can reliably read these multiple fluorophores in a high-throughput manner.
The PHERAstar Plus and the PHERAstar FS are the perfect instruments to handle these screens. Having Dual Emission Detection and the ability to read 1536-well microplates in less than a minute, the PHERAstar microplate readers make SNP Genotyping a snap.
For more information, check out this application note showing how the misread rate of SNP Genotyping using KASPar® is less than 0.1, while a recent publication shows how the PHERAstar and KASPar® have been used for the genetic mapping of Pigeonpea and Legumes.
