title: A phosphate bound universal linker for DNA synthesis.
abstract: A uridine-based linker immobilized onto polystyrene beads at the 5' terminus via a phosphodiester group and then used as a universal DNA synthesis support gives post synthesis DNA cleavage in 8 hrs or less without alkali metal salts. DNA produced with the new support was analyzed by HPLC, MALDI mass spectroscopy and PAGE. Each analysis showed DNA of equivalent quality to that produced with standard CPG supports, without contaminating materials resulting from linker or support backbone decomposition.
