Scanning of guanine-guanine mismatches in DNA by synthetic ligands using surface plasmon resonance.

Abstract excerpt

Here we have designed and synthesized ligands that specifically bind with high affinity (K(d) = 53 nM) to the guanine (G)-guanine mismatch, one of four types of single-nucleotide polymorphism (SNP). Detection of the G-G mismatch was performed by a surface plasmon resonance (SPR) assay using a sensor chip carrying the G-G specific ligand on its surface. The accuracy of the G-G mismatch detection by the SPR sensor...
