Abstract excerpt
A new method suitable for single nucleotide polymorphism detection and other applications based on oligonucleotide probe extension has been developed. The method is based on mass spectrometry and utilizes a single surface for affinity purification of extended probes and matrix-independent desorption/ionization of the cleavable labels. A new family of sulfur-linked laser-cleavable trityl labels with vastly...
