Disclosed herein are junction polypeptides that can be used, for example, to join together protein building blocks via a rigid fusion to generate a wide range of protein shapes; fusion proteins comprising such junction polypeptides, polymers thereof, and methods for designing such junction polypeptides.

Disclosed herein, inter alia, are methods and compositions for sequencing a plurality of template nucleic acids.

Technology provided herein relates in part to methods, processes, machines and apparatuses for determining sequences of nucleotides for nucleic acid templates in a nucleic acid sample. The technology provide herein also relates in part to methods, processes, machines and apparatuses for counting nucleic acid templates. Nucleic acid templates of a sample are tagged with nonrandom oligonucleotide adapters that include predetermined non-randomly generated sequences. The use of these nonrandom oligonucleotide adapters provides an efficient method to reduce sequencing errors, and increase the sensitivity of detection of low-frequency single nucleotide alterations.

Compounds, composition, and kits are provided for use in methods for the assisted folding of protein fragments of a of choice point larger protein by means of induced proximity, forced by specific nucleic acid hybridizations between a target nucleic acid molecule and complementary nucleic acid molecules appended to the protein fragments of interest.

The present invention provides a method for educating and expanding tumor infiltrating lymphocytes (TILs) into a therapeutic population of TILs for adoptive cell immunotherapy. Also provided are methods of treating cancer patients with the therapeutic population of TILs.

A method and reagent for constructing a nucleic acid double-linker single-strand cyclic library. The method comprises: breaking a nucleic acid into nucleic acid fragments; connecting a first linker sequence; producing by amplification a first product provided with the first linker sequence at either end, where a U nucleobase site is provided on primer sequences and a nicking enzyme recognition sequence is either provided or not provided on same, and a first affinity tag is provided on one of the primer sequences; using USER enzyme to cleave the first product; cyclizing the cleaved first product; treating the cyclization product with either a phosphatase or a nicking enzyme; using a solid-phase vector for combination with a cyclized molecule; performing a restrictive gap translation reaction; removing by digestion any portion that did not undergo the restrictive gap translation reaction; connecting a second linker sequence; producing by amplification a second product provided with the second linker sequence at either end; denaturing the second product, and cyclizing a single-strand nucleic acid molecule. The method allows an increase in the length of library insert fragments, a simplified library construction process, reduced library construction time, and reduced library construction costs.

The present disclosure describes software tools for effective biosecurity based on community knowledge and participation. Annotation tools described herein provide assistance to the synthetic biology community to track emerging science on the link between individual proteins and negative outcomes. Screening tools described herein enables the community to broaden both interest and effective practice of biosecurity so that practitioners and biological sequence or construct providers are empowered to evaluate the safety of order requests rather than waiting until synthesis or even expression. In addition, screening tools described herein provide for screening of polynucleotides across the same or multiple orders for sequences associated with harmful biological sequences from a reference database.

A method and reagent for constructing a nucleic acid double-joint single-strand cyclical library. The method comprises: breaking a nucleic acid into nucleic acid fragments; connecting a first linker sequence; producing by amplification a first product provided with the first linker sequence at either end, where a U nucleobase is provided on a primer sequence; using USER enzyme to cleave the first product and cyclizing to produce a gap; or, a nicking enzyme recognition sequence is also provided on the primer sequence, using the USER enzyme to cleave the first product, cyclizing and using a nicking enzyme for nicking to produce a nick; performing a restrictive nick/gap translation reaction from the nick or the gap; removing by digestion any portion that did not undergo the restrictive nick/gap translation reaction; connecting a second linker sequence; producing by amplification a second product provided with the second linker sequence at either end; denaturing the second product, and using a mediated sequence for cyclization of a single-strand nucleic acid molecule. The method allows an increase in the length of library insert fragments and obviates the need for gel extraction; the single-strand nucleic acid molecule can be cyclized directly when denatured with heat.

The invention is a novel method of separately sequencing each strand of a nucleic acid involving the use of an adaptor comprising a strand cleavage site or a strand synthesis termination site. The adaptor may also be self-priming at the strand cleavage site.

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.
