A primer useful as a first forward primer in performing digital PCR to detect a target nucleic acid in a sample, includes: a detection portion located upstream to a target sequence binding portion, and including a second forward primer binding portion having a sequence substantially complementary to a second forward primer, and a probe binding portion downstream to the second forward primer binding portion having a sequence substantially complementary to a probe; the target sequence binding portion includes a mismatch portion having a sequence not complementary to the target nucleic acid, and an amplification determinant portion downstream to the mismatch portion having a sequence complementary to a gene allele or a variant thereof encoded by the target nucleic acid.
Abstract: Provided herein are methods and compositions for the detection of target nucleic acids using target reporter constructs (TRCs) which comprise target sequences complementary to the target nucleic acid. Further provided are methods of replicating the TRCs using rolling circle replication and/or rolling circle amplification to produce replicated TRCs which can be detected using probe sequences within the replicated TRCs.

Abstract: The invention refers to a novel method of preparing strand-specific RNA-sequencing libraries that can be used to identify DNA coding and non-coding strands that are transcribed to RNA. Such strand-specific RNA-sequencing libraries are especially useful in discovering anti-sense RNA and non-coding RNA. Random primer oligonucleotides, covalently coupled to a moiety, which blocks ligation, are used for RT reaction or the subsequent generation of the second DNA strand so that only one strand of the generated double-stranded DNA is ligated to sequencing adapters at the 5? nucleotide and sequenced by paired-end sequencing.
Abstract: Compositions, kits, and methods are provided for the normalization of a quantitative polymerase chain reaction (PCR) amplification. Also provided are compositions, kits, and methods for multiplexing qPCR amplification of two or more target nucleic acids in the same well.
Abstract: Disclosed herein are methods for detecting presence of a target nucleic acid (such as an influenza virus nucleic acid) in a sample. In some embodiments, the methods include contacting the sample with a first probe capable of hybridizing to the target nucleic acid and a second probe capable of hybridizing to the target nucleic acid, contacting the resulting complex with one or more gap filling reagents, thereby producing a gap-filled target nucleic acid, isolating and amplifying the gap-filled target nucleic acid. The amplified gap-filled target nucleic acid covalently linked to the substrate is then detected, for example with a detectably labeled probe. Also disclosed herein are probes capable of hybridizing to influenza virus nucleic acids. The disclosure also includes kits for detecting and/or discriminating influenza virus nucleic acids in a sample. In some examples, the kits include two or more of the disclosed probes.
