ANTI-CRISPR CONSTRUCT AND ITS USE TO COUNTERACT A CRISPR-BASED GENE-DRIVE IN AN ARTHROPOD POPULATION
Publication number: 20240292819Abstract: The present invention relates to an anti-CRISPR construct useful to counteract the spread of a gene-drive in an arthropod population. The invention is also concerned with a system comprising the anti-CRISPR construct and a crispr-based gene-drive construct, a method of producing a genetically modified arthropod, a genetically modified arthropod, and a method for counteracting a CRISPR-based gene-drive in an arthropod population.Type: ApplicationFiled: June 23, 2022Publication date: September 5, 2024Applicants: Imperial College Innovations Limited, Polo D’Innovazione di Genomica Genetica e Biologia SRLInventors: Chrysanthi Taxiarchi, Roberto Galizi, Andrea Crisanti, Alekos Simoni, Rocco D'Amato -
Publication number: 20210251203Abstract: The invention relates to polynucleotides, and in particular to novel polynucleotides which represent promoter sequences. The invention is especially concerned with novel promoters for use in germline expression, in that they are substantially operative in only germline cells. In particular, the promoters initiate transcription of genes in the germline cells of an arthropod, and can be used in a gene drive. The invention is also concerned with vectors and gene drive constructs comprising the polynucleotides of the invention. The invention is also concerned with methods of producing arthropods comprising vectors containing such promoters.Type: ApplicationFiled: June 21, 2019Publication date: August 19, 2021Applicant: IMPERIAL COLLEGE OF SCIENCE, TECHNOLOGY AND MEDICINEInventors: Andrea Crisanti, Tony Nolan, Andrew Hammond

Publication number: 20210127651Abstract: The invention relates to gene drives, and in particular to genetic sequences and constructs for use in a gene drive. The invention is especially concerned with ultra-conserved and ultra-constrained sequences for use as a gene drive target with the aim of overcoming the development of resistance to the drive. The invention is also concerned with methods of suppressing wild type arthropod populations by use of the gene drive construct described herein.Type: ApplicationFiled: June 21, 2019Publication date: May 6, 2021Applicant: IMPERIAL COLLEGE OF SCIENCE, TECHNOLOGY AND MEDICINEInventors: Andrea Crisanti, Kyros Kyroi, Andrew Hammond

Publication number: 20170328892Abstract: The invention provides a method of quantifying multiple antigen-specific immunoglobulins in a test sample, the method comprising utilising a serial dilution of anti-immunoglobulin antibodies, fragments or derivatives thereof, immobilised on a solid support in combination with a serial dilution of a reference sample of immunoglobulin to generate multiple binding capacity curves. Such binding capacity curves are matched to specific dose response curves generated for each specific antigen to be tested using serum samples of known reactivity to those antigens to provide a calibration system that enables more accurate analysis of antigen-specific immunoglobulin in a sample. The invention also provides methods for calibrating a device suitable for assaying multiple antigen-specific immunoglobulins binding to multiple antigens or fragments thereof immobilised on a solid support. A multi-allergen test system and kits for use in the methods are also provided.Type: ApplicationFiled: May 26, 2017Publication date: November 16, 2017Applicant: Microtest Matrices LimitedInventors: Andrea Crisanti, Mauro Maccari, Francesca Baldracchini
