System and method for solid-phase parallel synthesis of a combinatorial collection of compounds
First Claim
1. A system for synthesizing chemicals on membrane supports in a parallel manner, the system comprising:
- a plurality of middle plates, with each middle plate comprising a plurality of holes arranged in a two dimensional array having x and y axes, wherein the middle plates are stackable on each other and adapted to receive a plurality of interleaving sheets of membrane to form a three dimensional array of reaction zones having x, y and z axes and defining Z (x,y) reaction planes, wherein each Z(x,y) reaction plane has a different sheet of membrane; and
a pair of end plates, wherein the middle plates are located between the end plates, and wherein the end plates include an array of fluid guides corresponding to said array of reaction zones, to allow for selective routing of reagents through the reaction zones such that the same reagent passes through the reaction zones having a common z axis.

Abstract
The invention provides a system and method for synthesizing chemicals onto supports in a parallel manner to produce a combinatorial collection of compounds. The system includes a plurality of middle plates, with each middle plate defining a plurality of reaction zones arranged in a two dimensional array. The reaction zones are adapted to receive a solid support, such as a sheet of membrane, and the middle plates are stackable on each other to form a three dimensional array of reaction zones. The system also includes a pair of end plates, where the middle plates are located between the end plates, and where the end plates include an array of fluid guides corresponding to the array of reaction zones, to allow for selective routing of reagents through the reaction zones.
