This report has described a convenient genotyping method capable of detecting point mutations directly in human genomic DNA based on the combination of ligase chain reaction (LCR) and microbead-enrichment technique. LCR primers, including a biotin-labeled common primer and two fluorescence-labeled allele-specific primers, are designed for two alleles of a mutated site. When genomic DNA carries the...
Melting curve analysis is a powerful tool for detecting single-base mutations that may be linked to genetic diseases. Current existing methods provide insignificant melting point difference for some point mutations with the risk of wrong genotyping results, causing great limitations to their applications in clinic diagnosis. Here, we have developed an enhanced melting point difference approach to...
