A lactate-responsive enzyme may form the basis for lactate detection and quantification using an electrochemical analyte sensor. Various features may be incorporated within an analyte sensor containing a lactate-responsive enzyme, particularly lactate oxidase, to improve sensitivity and response stability of the analyte sensor. Such analyte sensors may comprise: a working electrode having an active area disposed thereon, and a mass transport limiting membrane overcoating at least the active area upon the working electrode. The active area comprises at least a polymer, an albumin, and a lactate-responsive enzyme that is covalently bonded to the polymer. The mass transport limiting membrane may comprise at least a crosslinked polyvinylpyridine homopolymer or copolymer. The analyte sensors may determine a lactate concentration in a biological fluid, particularly in vivo, which may be correlated to various physiological conditions.

Lactate sensors and associated methods

In vivo monitoring devices and systems for enzymes and/or analytes including devices having a reactant reservoir are provided.

In vivo enzyme activity sensors and methods

Provided herein is technology relating to sequencing nucleic acids and particularly, but not exclusively, to methods, compositions, and systems for sequencing a nucleic acid using one or more labels and signal amplitude to distinguish bases.

DNA sequencing

Provided herein is technology relating to sequencing nucleic acids, but not exclusively, to compositions, methods, systems, and kits related to nucleotides comprising an electrochemically detectable moiety and one or more photolabile synthesis-inhibiting moieties.

Nucleotide analogs for sequencing

The present invention compositions, methods and systems to identify, detect, and/or quantify bacterial DNA in the presence of contaminating non-bacterial DNA. In particular, the present invention provides oligonucleotides configured to detect a relatively small amount of bacterial DNA in the presence of an overwhelmingly large amount of contaminating human DNA.

Bioagent detection oligonucleotides

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).

Sequencing by synthesis using pulse read optics

Provided herein is technology relating to sequencing nucleic acids and particularly, but not exclusively, to methods, compositions, and systems for sequencing a nucleic acid using two or more labels and signal ratios to distinguish bases.

Provided herein is technology relating to sequencing nucleic acids and particularly, but not exclusively, to methods, compositions, systems, and kits for sequencing a nucleic acid using a degenerate two-base code. Particular embodiments provide: 1) that the two-base degenerate code relates a first element to a base comprising adenine (A) or guanine (G) and a second element to a base comprising cytosine (C) or thymine (T); 2) that the two-base degenerate code relates a first element to a base comprising A or C and a second element to a base comprising G or T; and 3) that the two-base degenerate code relates a first element to a base comprising G or C and a second element to a base comprising A or T.

The present disclosure relates to systems and methods for nucleic acid ligation. In particular, the present disclosure provides oligonucleotide adaptors for use in nucleic acid ligation reactions.

Nucleic acid ligation systems and methods

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&#x2212; 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.

Rapid whole genome amplification

The present invention provides methods kits and systems for performing multiple displacement amplification reactions. In one method a sample of nucleic acid is provided. The nucleic acid is contacted with a reaction mixture which includes a set of oligonucleotide primers, a one or more polymerase enzymes and a detergent. The reaction mixture is then subjected to conditions under which the nucleic acid sequence is amplified to produce an amplified product in a multiple displacement reaction. The method may also be carried out by contacting the nucleic acid with the reaction mixture in the form of an emulsion. A kit is also provided for carrying out either the methods described above. The kit includes one or more polymerases, a plurality of primers and a detergent. The kit may also include a hydrophobic polymer and may include instructions for performing a multiple displacement amplification reaction on a nucleic acid sample.

Multiple displacement amplification

The present invention provides methods and kits for repair of degraded DNA which may then be used as a template for efficient amplification by a number of different amplification reactions. The method relies upon a series of enzymatic activities provided by DNA repair enzymes.
