Cover Story: Precise detection of KRAS codon 12 mutations is essential for cancer diagnosis and treatment selection. This study presents an elegant, single-tube fluorescence-based assay that integrates the ligase detection reaction (LDR) with magnetic bead capture. The method leverages four distinct fluorophores to simultaneously identify both wild-type and mutant alleles in genomic DNA extracted from colorectal cancer cells. By eliminating the need for electrophoresis or microarrays, this accessible platform demonstrates rapid, cost-effective genotyping using a standard spectrofluorometer, bringing molecular diagnostics closer to routine laboratory practice.
