  • Publication number: 20230076823
    Abstract: A technique for sequencing nucleic acids in an automated or semi-automated manner is disclosed. Sample arrays of a multitude of nucleic acid sites are processed in multiple cycles to add nucleotides to the material to be sequenced, detect the nucleotides added to sites, and to de-block the added nucleotides of blocking agents and tags used to identify the last added nucleotide. Multiple parameters of the system are monitored to enable diagnosis and correction of problems as they occur during sequencing of the samples. Quality control routines are run during sequencing to determine quality of samples, and quality of the data collected.

  • Patent number: 9765396
    Abstract: A technique is disclosed for recapturing and recycling biomolecule reagents. The technique may be applied in a range of settings, including biopolymer synthesis, sequencing, and so forth. Biomolecule reagents such as nucleotides and oligonucleotides used to process nucleic acids, which may be marked with fluorescent tags, carry blocking agents, and so forth, are introduced to samples in a sample container. After the desired reaction occurs with some of the biomolecule reagents, such as some of the nucleotides or oligonucleotides, the effluent stream is processed to recapture unreacted biomolecule reagents. These may be separated from other reaction components, and recycled into the same or a different sample container. The recaptured biomolecule reagents may be mixed with additional biomolecule reagents prior to reintroduction to the same or different samples.

  • Patent number: 9677194
    Abstract: A method of fabricating a microarray including the steps of: (a) contacting a substrate having wells with a reagent reactive with said substrate to produce a surface modification within said wells and a surface modification surrounding said wells; (b) polishing said substrate to produce a polished surface modification surrounding said wells, wherein said surface modification surrounding said wells is removed and said surface modification within said wells is retained, and (c) depositing a biopolymer onto said substrate, wherein different affinities of said surface modification within said wells and said polished surface facilitate localization of said biopolymer within said wells.
