Abstract:
A gene pen apparatus for delivering arrays of oligonucleotides on an array support comprising:(A) an array-forming printhead, said printhead comprising a body, a printing face, and a flow controlling means, said body having, a multiplicity of bores therethrough, said printing face comprising a multiplicity of fluid orifices, each of said fluid orifices being contiguous with at least one of said bores, said fluid orifices being spatially arranged in an array, and said flow controlling means is either a pin valve means or wicking member means, wherein the flow controlling means is located at the fluid orifices; and(B) a multiplicity of reagent reservoirs, each of said reagent reservoirs being fluidly connected to at least one of said bores at an end, each of said reagent reservoir being of sufficient volume to enable the printing of a multiplicity of said arrays.
