Microarrays having multiple oligonucleotides in single array features

Номер: GB0002409454A
Принадлежит:

The present invention is a method for synthesizing microarrays having different oligonucleotides present within one feature area of the array. The method utilizes the techniques common to miccroarray synthesis, but limits the duration in which selected feature areas on the array are initially dosed with light so as to only deprotect a calculated ratio of the compounds forming the array's binding layer. The compounds initially deprotected are capped with a nonphotosensitive protecting group, such as di-methoxy-trityl, to inhibit their involvement in the synthesis of a first group of DNA strands built onto the array. Once the first group of DNA strands have been synthesized, the original deprotected group may then be further processed to build one or more groups of DNA strands in the same feature area as the first group of DNA strands. The present invention also includes microarrays manufactured using the method.

The invention provides methods and kits for ordering sequence information derived from one or more target polynucleotides. In one aspect, one or more tiers or levels of fragmentation and aliquoting are generated, after which sequence information is obtained from fragments in a final level or tier. Each fragment in such final tier is from a particular aliquot, which, in turn, is from a particular aliquot of a prior tier, and so on. For every fragment of an aliquot in the final tier, the aliquots from which it was derived at every prior tier is known, or can be discerned. Thus, identical sequences from overlapping fragments from different aliquots can be distinguished and grouped as being derived from the same or different fragments from prior tiers. When the fragments in the final tier are sequenced, overlapping sequence regions of fragments in different aliquots are used to register the fragments so that non-overlapping regions are ordered. In one aspect, this process is carried out in a hierarchical fashion until the one or more target polynucleotides are characterized, e.g. by their nucleic acid sequences, or by an ordering of sequence segments, or by an ordering of single nucleotide polymorphisms (SNPs), or the like.

Self-Assembled Single Molecule Arrays and Uses Thereof

Номер: US20140073513A1
Принадлежит: Callida Genomics Inc

The present invention provides methods of making and using self-assembled arrays of single polynucleotide molecules for carrying out a variety of large-scale genetic measurements, such as gene expression analysis, gene copy number assessment, and the like. Random arrays used in the invention are “self-assembled” in the sense that they are formed by deposition of polynucleotide molecules onto a surface where they become fixed at random locations. The polynucleotide molecules fixed on the surface are then identified by direct sequence determination of component nucleic acids, such as incorporated probe sequences, or by other decoding schemes. Such identification converts a random array of determinable polynucleotides, and their respective probes into an addressable array of probe sequences.
