Multicolor fluorescence detection for single nucleotide polymorphism genotyping using a filter-less fluorescence detector

摘要

Single nucleotide polymorphism (SNP) analysis that is commonly performed using fluorescence is important in drug development and pathology research. In this study, to facilitate the analysis, multicolor fluorescence detection for SNP genotyping using a filter-less fluorescence detector (FFD) was investigated. FFDs do not require any optical filters for multicolor fluorescence detection. From the experimental results, FFD could identify 0μM, 1 μM, and 10 μM solutions of Texas Red and fluorescein isothiocyanate. Moreover, a mixture of Texas Red and 6-FAM could be detected in the SNP genotyping simulation. Therefore, a small and low-cost SNP genotyping system is feasible.
