Three-dimensional microarray platform applied to single nucleotide polymorphism analysis.
Abstract
Bio-Strand, Inc., has developed a novel DNA microarray platform utilizing a three-dimensional (3D) DNA format. DNA probes or polymerase chain reaction (PCR) products are spotted onto a thread-like scaffold, which is then wound onto a cylindrical core. By wrapping the thread around the core, high efficiencies are achieved in sample analysis. Using allele-specific oligo (ASO) competitive hybridization (with Cy5 fluorescently labeled sequences), hybridized arrays are visualized using a helium-neon (HeNe) laser and quantitated/scored. The method can readily detect single nucleotide differences. We demonstrate the use of this Bio-Strand 3D array in the analysis of a single nucleotide polymorphism (SNP).
