The present disclosure is directed to methods and/or uses of oligonucleotide conjugates for assays and flow cytometry detections and related systems and/or kits. Certain methods are directed to a method for detecting one or more biological targets of a sample in a detection assay, comprising: providing a molecular probe, comprising a binding moiety and an oligonucleotide sequence, to a sample comprising one or more biological targets; binding the one or more biological targets with the binding moiety; providing a detectable component to the sample, wherein the detectable component comprises a signal generating moiety conjugated to an oligonucleotide sequence complementary to the oligonucleotide sequence of the molecular probe; hydridizing the oligonucleotide sequence of the target-bound molecular probe to the detectable component; and detecting a signal generated from the hydridized detectable component. Various other embodiments, applications etc. are disclosed herein.

Provided herein, in some embodiments, are methods, compositions and kits for large-scale production of long single-stranded DNA in solution.

A target (50) having a specific nucleic acid sequence included in a sample is measured using a detection probe (10) that has a detection part having a nucleic acid sequence complementary to the nucleic acid sequence of the target (50), a label molecule A (20) having a nucleic acid sequence that is complementary to the nucleic acid sequence of the target (50) and different from the nucleic acid sequence of the detection part, and a label molecule B (30) having a nucleic acid sequence complementary to the nucleic acid sequence of the label molecule A (20), in which a fluorescent molecule is attached to either one of the label molecule A (20) and the label molecule B (30), and the label molecule A (20) and the label molecule B (30) bind to each other at at least two or more sites to form a branched structural body of the label molecule A (20) and the label molecule B (30).

The present invention refers to methods for selectively recognizing a base pair in a DNA sequence by a polypeptide, to modified polypeptides which specifically recognize one or more base pairs in a DNA sequence and, to DNA which is modified so that it can be specifically recognized by a polypeptide and to uses of the polypeptide and DNA in specific DNA targeting as well as to methods of modulating expression of target genes in a cell.

The present invention relates to the field of nucleic acid purification. In particular, it relates to methods and tools for purifying nucleic acids in a sample; which are compatible with high-throughput sequencing and diagnosis. The inventors have shown that nucleic acid binding proteins recruited to polymerized tubulin (i.e. microtubules) could, subsequently, be isolated from cell lysates. Surprisingly, it has now been found that the amount of recovered nucleic acid found in these microtubule pellets increases dramatically in the presence of nucleic acid-trapping proteins comprising a nucleic acid-binding moiety and a polymerized tubulin-binding moiety, by comparison to proteins devoid of the nucleic acid-binding moiety; and that the recovery of the purified nucleic acids was itself particularly efficient. This purification method is particularly amenable to high-throughput sequencing and/or in the context of a diagnosis method for identifying or comparing the amount of nucleic acids in a set of samples.
