Abstract:
Disclosed are systems and methods for polynucleotide sequencing where detection and correction of base calling errors can be achieved without reliance on a reference sequence. In certain embodiments, redundant information, which may be provided by additional labels, can be introduced during measurement so as to allow such detection of errors. Such redundant information and measurements can be facilitated by encoding of nucleotide sequence being measured. Various examples of such encoding, redundancy introduction, and decoding are provided.
Abstract:
A method of conjugating a substrate includes exchanging a counter ion associated with a biomolecule with a lipophilic counter ion to form a biomolecule complex, dispersing the biomolecule complex in a non¬ aqueous solvent, and coupling the biomolecule complex to a sub¬ strate in the presence of the nonaqueous solvent. The substrate or solid support is a polymeric particle, the biomolecule to be immo¬ bilized on the particle is an oligonucleotide, the lipophilic counter ion is a tetrabutylammonium ion and the nonaqueous solvent is N- methylpyrrolidone (NMP). The oligonucleotide coated particles are used in nucleic acid isolation or in nucleic acid sequencing reactions.
Abstract:
Flowcell designs that are suitable for large scale gene sequencing analyses are disclosed. Different layouts of flowcells are presented. Methods of functionalizing the surface where DNA samples are placed for enhanced attachment are discussed. Special treatments of the functionalized surface to achieve desired optical characteristics are also featured.
Abstract:
Provided herein are compositions, materials, methods and kits for immobilizing a template polynucleotide in a first orientation, and immobilizing a complementary sequence of the template polynucleotide in an orientation that is flipped compared to the orientation of the template polynucleotide. Provided herein are adaptive oligonucleotides that can be used in various nucleic acid manipulations to generate immobilized complement polynucleotides that are flipped in orientation compared to the orientation of the immobilized template polynucleotides.
