Abstract

We have evaluated in a microchip format the photochemical solid-phase phosphoramidite DNA synthesis method we previously developed. A set of nucleoside building blocks with “easy-off” base protecting groups was prepared bearing photolabile 5'-O- dimethoxybenzoincarbonate (DMBOC) groups. Photolysis rates and cycle yields for these DMBOC-protected nucleotides covalently attached to planar, derivatized glass surfaces ...
