Abstract:
A synthetic strategy for the creation of large scale chemical diversity. Solid-phase chemistry, photolabile protecting groups, and photolithography are used to achieve light-directed spatially-addressable parallel chemical synthesis. Binary masking techniques are utilized in one embodiment. A reactor system, photoremovable protective groups, and improved data collection and handling techniques are also disclosed. A technique for screening linker molecules is also provided.
Abstract:
A method and library for determining the sequence of monomers in a polymer which is complementary to a receptor. The method provides for formation of pooled (6) and separate (10, 12) products. Separate products are subjected only to subsequent pooled coupling steps. Each pooled product is subsequently divided for formation of pooled and separate products. The resulting polymer library includes groups of polymer products. A first group of products (42) is used to identify the monomer at a first location in a polymer that is complementary to a receptor. A second group of products (44) is used to identify the monomer at a second location in a polymer that is complementary to a receptor.
Abstract:
A method and apparatus for preparation of a substrate containing a plurality of sequences. Photoremovable groups are attached to a surface of a substrate. Selected regions of the substrate are exposed to light so as to activate the selected areas. A monomer, also containing a photoremovable group, is provided to the substrate to bind at the selected areas. The process is repeated using a variety of monomers such as amino acids until sequences of a desired length are obtained. Detection methods and apparatus are also disclosed.

Abstract:
This invention provides oligonucleotide based arrays and methods for speciating and phenotyping organisms, for example, using oligonucleotide sequences based on the Mycobacterium tubercluosis rpoB gene. The groups or species to which an organism belongs may be determined by comparing hybridization patterns of target nucleic acid from the organism to hybridization patterns in a database.

Abstract:
A library for determining the sequence of monomers in a polymer which is complementary to a receptor includes groups of pooled polymer products; wherein each pool is ordered such that a monomer sequence which binds to a receptor can be identified from the pool order in the library.
Abstract:
A method and apparatus for selectively applying a print material onto a substrate for the synthesis of an array of oligonucleotides at selected regions of a substrate. The print material includes a barrier material, a monomer sequence, a nucleoside, a deprotection agent, a carrier material, among other materials. The method and apparatus also relies upon standard DMT based chemistry, and a vapor phase deprotection agent such as solid TCA and the like.
