The present invention relates to complexes of oligonucleotide-encoded libraries and methods of tagging and using such libraries. In particular, the oligonucleotides and methods can include complexes having at least one linkage for which a polymerase has reduced ability to read or translocate through.

Provided is a method of constructing a sequencing library. The method includes 1) providing a single-stranded DNA fragment from a biological sample; 2) subjecting the single-stranded DNA fragment to whole genomic amplification to obtain a whole genome amplification product; 3) fragmenting the whole genome amplification product using a transposase embedded with two adaptors to obtain a fragmented product with two adaptors respectively at two ends; and 4) amplifying the fragmented product with two adaptors respectively at two ends using a tag sequence and a pair of primers to obtain said sequencing library.

The present invention provides nucleic acid templates (e.g., including orthogonal codon sets (e.g., codons from orthogonal codon sets depicted in Tables 5 or 7)) for DNA-templated methods of synthesizing, selecting, and amplifying compounds (e.g., polymers and/or small molecules) described herein. Also provided are novel macrocyclic compounds of Formula (I), and pharmaceutically acceptable salts, solvates, hydrates, polymorphs, co-crystals, tautomers, stereoisomers, isotopically labeled derivatives, prodrugs, libraries, and compositions thereof. Also provided are methods and kits involving the inventive compounds or compositions for treating and/or preventing a disease (e.g., a disease associated with aberrant enzyme activity (e.g., aberrant protease and/or kinase activity (e.g., aberrant IDE activity)), impaired insulin signaling, or insulin resistance in a subject (e.g., a subject having diabetes). Treatment of a subject with a proliferative disease using a compound or composition of the invention may inhibit aberrant protease activity (e.g., aberrant IDE activity).

An effective sequencing method, the method comprising: (1) performing first sequencing on a sequencing template on a chip surface, so as to facilitate obtaining first sequencing data by means of first newly generated sequencing strands being formed, the sequencing template being connected onto the chip surface by means of a sequencing adapter; (2) performing first blocking treatment on 3′ ends of at least a portion of the first newly generated sequencing strands; and (3) performing second sequencing on the sequencing template, so as to facilitate obtaining second sequencing data by means of second newly generated sequencing strands being formed.

The present invention relates to a method of preparing a gene cluster construct including a plurality of genes encoding a multi-modular biosynthetic enzyme, the method including (A) a step of preparing a plurality of DNA fragments which are capable of reconstructing the gene cluster construct and have structures that can be ligated to each other and (B) a step of ligating the plurality of DNA fragments prepared in the step (A) to each other by mixing the plurality of DNA fragments in a solution to obtain the gene cluster construct.
