Methods, systems, kits and compositions are described for quality control and quantitation of nucleic acid libraries of double stranded nucleic acid libraries prior to massively parallel sequencing. Electrophoretic separation within a channel using a detectably labeled single stranded sizing ladder may be used to define the molecular weight range and amount of the double stranded nucleic acids.

The present disclosure in some aspects relates to methods for detecting a target analyte in a sample by a method comprising rolling circle amplification (RCA) and hybridisation chain reaction (HCR).

The present disclosure in some aspects relates to methods for detecting a target analyte in a sample by a method comprising rolling circle amplification (RCA) and hybridisation chain reaction (HCR).

In some aspects disclosed herein are methods and compositions for detecting a target nucleic acid molecule, said method comprising performing a linear oligo hybridization chain reaction (LO-HCR) to generate a polymeric product, and detecting the polymeric product, thereby detecting the target nucleic acid molecule.

The present report relates to hybridizing single-stranded (ss-) oligonucleotides which entirely consist of locked nucleic acid (LNA) monomers. The present document shows hybridization experiments with pairs of entirely complementary ss-oligonucleotides which fail to form a duplex within a given time interval. The present report provides methods to identify such incompatible oligonucleotide pairs. In another aspect, the present report provides pairs of complementary ss-oligonucleotides which are capable of rapid duplex formation. The present report also provides methods to identify and select compatible oligonucleotide pairs. In yet another aspect the present report provides use of compatible oligonucleotide pairs as binding partners in binding assays, e.g. immunoassays.

Methods and materials are provided for detecting nucleic acid sequence differences including single nucleotide mutations or polymorphisms, one or more nucleotide insertions, and one or more nucleotide deletions in single molecule target members present in a test population of nucleic acid fragments. Heteroduplexes are formed between members of the test nucleic acid population and their corresponding complements provided in a pool of mismatch cleavage probes. Mismatched base pairs in the heteroduplexes are specifically cleaved and cleaved probe fragments are electronically detected to signal the present of the target members in the test population.
