Spotting pattern for placement of compounds in an array

摘要

A plurality of samples of different substances are tested for their ability to enhance or inhibit a biological process. The samples are deposited on a supporting surface, such as a ChemCard, in an array comprising at least two dots of each sample, wherein at least one of the dots of each sample is at least a predetermined distance from at least one of the dots of each of the plurality of samples. One or more assay reagents in a gel sheet, for example, are then brought in contact with the compounds and reactions with certain of the compounds are evident as the active compounds diffuse into the one or more assay reagents. The concept of having unique neighbors for each occurrence of a dot allows the definitive correlation of active compounds with the dot (and the compound) that caused the biological activity.
