Abstract
Abstract A method to produce arrays of compounds for concurrent testing is described. Two formats are described using porous rods or porous sheet materials. In one format the compounds of the array are immobilized to porous rod elements. In the second format the compounds are immobilized as lines on a sheet of porous material. In both cases, a bundle is formed by radial compression of the rods or spiral wrapping of the sheet. A sheath is applied to the bundle and arrays are cut as slabs. Each synthesis or application step to create an array element is used to fabricate multiple arrays. Relatively high density arrays can be produced with current printing technologies. The method is particularly suited to mass production of arrays.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
105 words
A method for forming an array for detecting components in a sample mixture, which comprises a. immobilizing binding compounds specific for detecting said components onto a sheet of material by forming lines with the binding compound on the sheet; b. forming a bundle of compounds in a generally elongated form by collecting the sheet containing the immobilized compounds about a common axis to form an elongated bundle and wrapping the sheet in a spiral; and c. cutting individual arrays into slices from the bundle to generate a spatially uniform arrangement of compound samples and sheet of material generally in a plane intersecting the common axis.
Claim 2
Independent Claim
105 words
A method for forming an array for detecting components in a sample mixture, which comprises a. immobilizing binding compounds specific for detecting said components onto a sheet of material by forming lines with the binding compound on the sheet; b. forming a bundle of compounds in a generally elongated form by collecting the sheet containing the immobilized compounds about a common axis to form an elongated bundle and wrapping the sheet in a spiral; and c. cutting individual arrays into slices from the bundle to generate a spatially uniform arrangement of compound samples and sheet of material generally in a plane intersecting the common axis.
