Specific Gene Capture Combined with Restriction-Fragment Release for Directly Fluorescent Genotyping of Single-Nucleotide Polymorphisms in Diagnosing Spinal Muscular Atrophy.

Abstract excerpt

In this study, a fast and simple fluorescent genotyping strategy, streptavidin magnetic beads combined with biotin-coupled PCR and restriction-fragment release, was developed for determination of nucleotide variants. This method was further applied for analyzing SMN1 gene in diagnosis of spinal muscular atrophy (SMA). After biotin-coupled PCR, the streptavidin magnetic beads would capture the biotin-labeled SMN...
