A method and device for forming large arrays of polymers on a substrate (401). According to a preferred aspect of the invention, the substrate is contacted by a channel block (407) having channels (409) therein. Selected reagents are flowed through the channels, the substrate is rotated by a rotatin
A method and device for forming large arrays of polymers on a substrate (401). According to a preferred aspect of the invention, the substrate is contacted by a channel block (407) having channels (409) therein. Selected reagents are flowed through the channels, the substrate is rotated by a rotating stage (403), and the process is repeated to form arrays of polymers on the substrate. The method may be combined with light-directed methodolgies.
A method of forming a plurality of peptide sequences on a surface of a single substrate comprising the steps of: a) contacting said substrate with a channel block in a first orientation, said channel block comprising a substantially planar member with a plurality of recessed regions and raised walls
A method of forming a plurality of peptide sequences on a surface of a single substrate comprising the steps of: a) contacting said substrate with a channel block in a first orientation, said channel block comprising a substantially planar member with a plurality of recessed regions and raised walls on a surface thereof, said recessed regions forming channels, said raised walls effective to produce substantially fluid-tight seals between said raised walls and said substrate upon said contacting to define thereby a first plurality of flow channels between said channel block and said substrate, said first flow channels dividing said substrate surface into at least a first portion and a second portion; b) flowing at least a first amino acid through at least one of said first flow channels, and convalently coupling said first amino acid to said first portion of said substrate surface, said first amino acid comprising a reactive group protected by a protecting group; c) flowing at least a second amino acid through at least one of said first flow channels, and covalently coupling said second amino acid to said second portion of said substrate surface, said second amino acid comprising a reactive group protected by a protecting group; d) translating said channel block relative to said substrate and contacting said substrate with said channel block in a second orientation to produce substantially fluid-tight seals between said raised walls and said substrate upon said contacting to define thereby a second plurality of flow channels between said channel block and said substrate, said second flow channels dividing said substrate surface into at least a third portion and a fourth portion, said third and fourth portions each having at least one intersection with each of said first and second portions of said substrate surface; e) removing said protective groups from at least a portion of said first or second amino acids to form a first set of deprotected first or second amino acids and flowing a third amino acid through at least one of said second flow channels, covalently coupling said third amino acid to said third portion of said substrate surface and covalently coupling said third amino acid to at least a portion of said firs set of deprotected first or second amino acids through a peptide bond therewith where said first and second portions of said substrate surface intersect with said third portion of said substrate surface to form first and second peptide sequences; and f) removing said protective group from at least a portion of said first and second amino acids to form a second set of deprotected first or second amino acids and flowing a fourth amino acid through at least one of said second channels, covalently coupling said fourth amino acid to said fourth portion of said substrate surface and covalently coupling said fourth amino acid to at least a portion of said second set of deprotected first or second amino acids through a peptide bond therewith where said fourth portion of said substrate intersects with said first and second portions of said substrate surface to form third and fourth peptide sequences.
