Abstract
A method and apparatus for nucleic acid synthesis. The method employs a device including at least one deprotection unit to carry out a step of deprotection, at least one coupling unit to carry out a step of coupling, at least one oxidation/thiolation unit to carry out a step of oxidation or thiolation, at least one capping unit to carry out a step of capping, and at least one washing unit to carry out a step of washing. A plurality of reaction vessels for nucleic acid synthesis are moved to the units in accord with a synthesis scheme for a desired nucleic acid sequence and at least two reaction vessels are simultaneously acted upon at several of the units in series.
