  • Publication number: 20260079163
    Abstract: Characterization of the binding dynamics at the interface between any two proteins that specifically interact plays a role in myriad biomedical applications. The methods disclosed herein provide for the high-throughput characterization of the specific interaction at the interface between two protein binding partners and the identification of functionally significant mutations of one or both protein binding partners. For example, the methods disclosed herein may be useful for epitope and paratope mapping of an antibody-antigen pair, which is useful for the discovery and development of novel therapies, vaccines, diagnostics, among other biomedical applications.

  • Publication number: 20240360439
    Abstract: Provided are methods for resolving the relationship between unique user-designed and/or random synthetic DNA barcodes and a protein-coding mutated region of interest with enhanced accuracy that is amenable to short-read sequencing platforms. In addition, the methods introduce increased sequence divergence between mutational variants of a region of interest in order to enhance the resolvability of mutational variants within a mutagenic library when error-prone long-read sequencing platforms are used.

  • Patent number: 10689684
    Abstract: This disclosure describes techniques to improve the sequencing of polynucleotides by decreasing the likelihood of errors occurring during a sequencing calibration process. In implementations, regions of polynucleotides that are used for the calibration process can be modified to reduce a number of polynucleotides that have a same nucleotide at one or more positions of the calibration regions. In some cases, the calibration regions can be modified by adding a sequence to the polynucleotides that replaces the original calibration regions. Also, the calibration regions can be modified by rearranging the nucleotides at the different positions of the calibration regions. Additionally, the calibration regions can be modified by adding sequences of varying length to the polynucleotides being sequenced to produce polynucleotides having varying length with different calibration regions.
