Continuous format high throughput screening
First Claim
1. A process to simultaneously test a multitude of samples of different substances for their ability to enhance or inhibit a biological process comprising,a) depositing in an array a small volume of each of more than 96 samples of distinct substances onto a planar porous matrix containing or carrying a uniformly dispersed assay reagent such that each distinct substance is centered at its own distinct site and the identity of each substance can be determined from its deposition site, andb) observing the interaction of each substance with said assay reagent and correlating it to said substance'"'"'s ability to enhance or inhibit said biological process.

Abstract
Continuous format high throughput screening (CF-HTS) using at least one porous matrix allows the pharmaceutical industry to simultaneously screen large numbers of chemical entities for a wide range of biological or biochemical activity. In addition, CF-HTS is useful to perform multi-step assays.

2. A process to simultaneously test a multitude of samples of different substances for their ability to enhance or inhibit a biological process comprising,
a) depositing in an array a small volume of each of more than 96 samples of distinct substances onto a planar matrix such that each distinct substance is centered at its own distinct site and the identity of each substance can be determined from its deposition site, b) bringing said matrix into contact with a porous matrix containing or carrying a uniformly dispersed assay reagent and allowing some of each substance to diffuse into said porous matrix in a manner that the spacial location of each diffused substance can be correlated to the site on said planar matrix at which said substance was originally deposited, and c) conducting an assay to determine the ability of each diffused substance to enhance or inhibit said biological process.

3. A process to simultaneously test a multitude of samples of different substances for their ability to enhance or inhibit a biological process comprising,
a) depositing in an array a small volume of each of more than 96 samples of distinct substances onto a planar matrix such that each distinct substance is centered at its own distinct site and the identity of each substance can be determined from its deposition site, b) bringing said planar matrix into contact with a first porous matrix containing or carrying a uniformly dispersed first assay reagent and allowing some of each substance to diffuse into said porous matrix in a manner that the spacial location of each diffused substance can be correlated to the site on said planar matrix at which said substance was originally deposited, c) bringing said first porous matrix into contact with a second matrix carrying or containing a second uniformly dispersed assay reagent and allowing the second assay reagent to diffuse into the first porous matrix or allowing each substance and the first reagent to diffuse into the second matrix, in the latter case assuring that the diffusion occurs in such a manner that the location of each substance in the second matrix can be correlated to the site on said planar matrix at which said substance was originally deposited, and d) evaluating the ability of each substance to enhance or inhibit said biological process.

4. A process to simultaneously test a multitude of samples of different substances for their ability to enhance or inhibit a biological process comprising,
a) depositing in an array a small volume of each of more than 96 samples of distinct substances onto a first planar porous matrix containing or carrying a uniformly dispersed first assay reagent such that each distinct substance is centered at its own distinct site and the identity of each substance can be determined from its deposition site, b) bringing said first porous matrix into contact with a second planar matrix carrying or containing a second uniformly dispersed assay reagent and allowing the second assay reagent to diffuse into the first porous matrix or allowing each substance and the first reagent to diffuse into or onto the second matrix, in the latter case assuring that the diffusion occurs in such a manner that the location of each substance in or on the second matrix can be correlated to the site on said first porous matrix at which said substance was originally deposited, and c) evaluating the ability of each substance to enhance or inhibit said biological process.
