Provided herein are reagents for improving PCR accuracy.

Reagents for improving PCR accuracy

Provided herein are kits for performing for nucleic acid sequences.

Kits and reaction mixtures for analyzing single-stranded nucleic acid sequences

Homogenous detection during or following PCR amplification, preferably LATE-PCR, utilizing fluorescent DNA dye and indirectly excitable labeled primers and probes, improves reproducibility and quantification. Low-temperature homogeneous detection during or following non-symmetric PCR amplification, preferably LATE-PCR, utilizing fluorescent DNA dye and indirectly excitable labeled mismatch-tolerant probes permits analysis of complex targets. Sequencing sample preparation methods following LATE-PCR amplifications reduce complexity and permit 'single-tube' processing.

Methods for sequential DNA amplification and sequencing

Provided herein are methods, kits, and compositions related to nucleic acid detection assays that allow discrimination of multiple target sequences with a single probe. In particular, provided herein are methods kits, and compositions that include single-probe target sequence discrimination where different target amplicons may have identical probe hybridization sequences by employing multiple temperature end-point signal probe detection. Also provided herein are methods, kits, and compositions for distinguishing between two or more target amplicons using multiple-temperature end-point probe detection. In certain embodiments, asymmetric PCR amplification methods are employed (e.g., LATE-PCR amplification).

Single probe, multiple temperature, nucleic acid detection methods, kits, and compositions

Provided herein are methods, kits, and compositions related to nucleic acid detection that allow the detection and discrimination of variousspecies and types. In particular, provided herein are assays that allow the detection of MSSA, MSSE, MRSA, MRSE, VRSA, VRSE, and MRSA community strain by detecting the presence of absence of one or more target sequences selected from a list of target genes and sequences that include, but are not limited to: mecA, femA-SA, femA-SE, lukF-PV, lukS-PV, VanA, SCCmec type I, type II, type III, type IV, type V, and type VII. In certain embodiments, asymmetric PCR amplification methods are employed. In other embodiments, probe-target generated signals are detected at least two temperatures to generate a temperature/temperature signal ratio.

[object Object]

An assay comprising more than one primer pair and more than one detection probe, a low copy number synthetic amplicon corresponding to each of the primer pairs. The assay can detect and distinguish between various sub-types and strains of an influenza virus using any suitable nucleic acid amplification technique. Related kits and methods are also described.
