Embodiments of the compositions include partially double stranded polynucleotides for use as 3′ adapters that contain a cleavable linker positioned between a single-stranded region and a double-stranded region. Upon ligating the 3′ adapters, the single-stranded region is released by cleaving the cleavable linker.
Kits and methods are described that are directed to specific and sensitive methods of target nucleic acid detection and more specifically detecting target nucleic acids directly from biological samples. The kits and methods were developed to be easy to use involving a minimum number of steps and giving rapid and consistent results either at point of care or in high throughput situations. The kits and methods utilize in various combinations, reversible inhibitors of kit components, thermolabile enzymes, poloxamers, various salts, indicators and one or more Loop-Mediated Isothermal Amplification (LAMP) primer sets for detecting single and/or multiple targets and variants of the targets including SARS-CoV-2 targets and variants thereof in a single reaction. The kits and methods permit detection of the target nucleic with similar sensitivity regardless of the presence of undefined mutations that may enhance the virulence of cells or viruses containing the undefined mutations.

Provided herein is a method for chemically capping polynucleotides having a 5′ monophosphate. In some embodiments the method may comprise: combining an activated nucleoside 5′ mono- or poly-phosphate with a population of polynucleotides that comprises polynucleotides having a 5′ monophosphate, to produce a reaction mix; and incubating the reaction mix to produce reaction products that comprise a polynucleotide and a 5′ nucleoside cap, linked by a 5′ to 5′ polyphosphate linkage. The chemical capping method described herein can be incorporated into a variety of cDNA synthesis methods.
Ordered assembly of large numbers of fragments into a single large DN A have been improved in both frequency and fidelity of the assembled product. This has been achieved by novel compositions and methods that are utilized in a computer system that integrates comprehensive ligation data from multiple sources to provide optimized synthetic overhangs or overhangs from restriction endonuclease cleavage on DIMA fragments for assembly by ligation. Intragenic cut sites are avoided by the use of a novel restriction endonuclease which recognizes 7 nucleotides (bases) and cuts DNA to create 4-base overhangs with the help of a synthetic activator oligonucleotide. Variations in ligation preferences by different ligases provide extra precision in assembly reactions. The use of the improved methods are exemplified by the successful assembly from 52 fragments of a viral genome and also a 52 fragment ordered assembly of a bacteria operon.

A composition and its uses and additionally a kit are provided. The composition is a synthetic self-complementary oligonucleotide that has a double-stranded region and a loop, wherein the double-stranded region contains a binding sequence for PaqCl. Additionally, the oligonucleotide includes unligatable 3′ and 5′ ends that cannot be cleaved by PaqCl. This oligonucleotide composition has been combined with PaqCl or a variant of PaqCl Type IIS restriction endonuclease in a reaction mixture, where the reaction mixture includes PaqCl or variant that can further be combined with a ligase and optionally a deadenylase, crowding molecule such as PEG and/or a repair enzyme such as Endo MS. The kit includes the oligonucleotide and Type IIS restriction endonuclease in the same or different containers.
The present disclosure relates, according to some embodiments, to methods for preparing a library for sequencing. For example, a method may comprise (a) in a coupled reaction, (i) contacting a population of nucleic acid fragments with a tailing enzyme to produce tailed fragments, and (ii) ligating to the tailed fragments a sequencing adapter with a ligase to produce adapter-tagged fragments; and/or separating adapter-tagged fragments from the tailing enzyme and the ligase to produce separated adapter-tagged fragments and, optionally, separated tailing enzyme and/or separated ligase. In some embodiments, a tailing enzyme and/or a ligase used in library preparation may be immobilized enzymes.
