Abstract: The present invention relates to a method of covalently attaching a chromosome within a cell to a matrix including modifying a plurality of nucleotides within the chromosome to include a matrix attachment moiety wherein the chromosome contacts the matrix, and attaching the matrix attachment moiety of the plurality of nucleotides to the matrix, thereby attaching the chromosome to the matrix.

Abstract: The present invention relates to a method of identifying a target genomic nucleic acid sequence including hybridizing a set of probes to the target genomic nucleic acid sequence, wherein the set of probes has a unique associated barcode sequence for identification of the target genomic nucleic acid sequence, wherein each probe of the set includes (1) a complementary sequence complementary to a first strand of the target genomic nucleic acid sequence and (2) the associated barcode sequence or a portion of the associated barcode sequence, sequencing the associated barcode sequence from probes hybridized to the target genomic nucleic acid sequence using a fluorescence-based sequencing method, and identifying the target genomic nucleic acid sequence by the sequenced barcode sequence.
