The present invention provides systems, methods, and compositions for performing molecular tests. In particular, the present invention provides methods, compositions and systems for generating target sequence-linked solid supports (e.g., beads) using a solid support linked to a plurality of capture sequences and capture primers composed of a 3 target-specific portion and a 5 capture sequence portion. In certain embodiments, the target sequence linked solid support is used in sequencing methods (e.g., pyrosequencing, zero-mode waveguide type sequencing, nanopore sequencing, etc.) to determine the sequence of the target sequence (e.g., in order to detect the identity of a target nucleic acid in sample).

The present invention provides compositions and methods for rapidly amplifying target nucleic acid (e.g., using whole genome amplification) that allows small amounts of starting nucleic acid to be employed. In certain embodiments, the methods employ compositions that comprise: phi29 polymerase, exo-Klenow polymerase and/or Klenow polymerase, dNTPs, primers, and a buffering agent. In some embodiments, the target nucleic acid is amplified at a rate that would result in at least 1000-fold amplification in thirty minutes.

Provided herein are systems and methods for nucleic acid sequencing by synthesis in a plurality of wells using detectably labeled chain terminating nucleotides with photolabile blocking groups and pulses of photocleaving light. In certain embodiments, the systems and methods provides a plurality of deblock-scan cycles comprising an initial deblock time period followed by a scanning light period, wherein at least one of the following occurs in each deblock-scan cycle: 1) the deblock time period is shorter than the scan time period; 2) the deblock time period is only long enough to deblock the photolabile groups that are part of a primer in less than all of the plurality of wells; or 3) the deblock time period is between 25 and 150 mSec and the scan time is at least 200 mSec. Such shorter deblock time periods help prevent the addition of more than one nucleotide to the primer prior to scanning (e.g., accuracy is enhanced).

Patent
Ibis Biosciences | Date: 2016-11-30

The present invention provides systems, methods, and compositions for nucleic acid detection based on non-mass determined base compositions. For example, in certain embodiments, base count data for a template nucleic acid is generated using an approach that does not measure molecular mass of the template nucleic acid (e.g., by sequencing the template nucleic acid) and a database comprising base count entries is queried to identify the target nucleic acid. In particular embodiments, sequencing is employed which is conducted in substantially real-time.
