  • Publication number: 20250019756
    Abstract: A chemically-enhanced primer is provided comprising a negatively charged moiety (NCM), an oligonucleotide sequence having a) non-nuclease resistant inter-nucleotide linkages or b) at least one nuclease resistance inter-nucleotide linkage. The chemically-enhanced primer can be used for sequencing and fragment analysis. Methods for synthesizing the chemically-enhanced primer as well as a method of preparing DNA for sequencing, a method of sequencing DNA, and kits containing the chemically-enhanced primer are also provided. The method of sequencing DNA can comprise contacting amplification reaction products with the composition wherein excess amplification primer is degraded by the nuclease and the chemically-enhanced primer is essentially non-degraded.

  • Publication number: 20250019757
    Abstract: According to various embodiments described herein, a microfluidics-chip based purification device and system for Sanger-sequencing reactions is provided. The device and system allow for the introduction into a sequencing system of a cartridge containing purification technologies specific to the sequencing contaminants or sequencing method where the simplified purification solution of a cartridge allows automation of the sample purification process, reduced consumption of purification reagents, and consistency in sampling by reducing the sampling errors and artifacts. These various embodiments therefore solve the need for a microfluidics-chip-based, Sanger-sequencing reaction purification system for CE devices. The microfluidic chips described can be used as a PCR chip by reorganizing the on-chip reagents, reaction wells and work flow steps.

  • Patent number: 12049637
    Abstract: The present invention relates to cytolytic bi-component protein complexes consisting of a plurality of molecules of a member of the aegerolysin family and a plurality of molecules of a member of the MACPF superfamily, and particularly to their use for controlling a plant pest, such as for controlling Colorado potato beetle (Leptinotarsa decemlineata) or Western corn rootworm (Diabrotica virgifera virgifera). More specifically, the invention relates to cytolytic bi-component protein complexes formed by a plurality of molecules of one of the aegerolysins ostreolysin A6 (OlyA6), pleurotolysin A2 (PlyA2) and erylysin A (EryA) with a plurality of molecules of pleurotolysin B (PlyB) or similar proteins, which have been shown to be toxic for the aforementioned agricultural pest insects.

  • Publication number: 20210323871
    Abstract: A non-spray-drying, dry-granulation process for making a ceramic particulate mixture including from 4 wt % to 9 wt % water. At least 90 wt % of the particles have a particle size of from 80 ?m to 600 ?m. The process includes the steps of: (a) forming a precursor material; (b) subjecting the precursor material to a compaction step to form a compacted precursor material; (c) subjecting the compacted precursor material to a crushing step to form a crushed precursor material; and (d) subjecting the crushed precursor material to at least two air classification steps. One air classification step removes at least a portion of the particles having a particle size of greater than 600 ?m from the crushed precursor material, and the other air classification step removes at least a portion of the particles having a particle size of less than 80 ?m from the crushed precursor material.
