Publication number: 20230123603Abstract: The present invention relates to the field of genotyping samples containing short tandem repeat (STR) loci. More specifically, the present invention discloses a composition of matter containing an array of probes and a method to genotype these loci relying on the recognition of RNA:DNA base pairing followed by cleavage of the RNA containing strand. By measuring the temperature at which the chimeric DNA-RNA-DNA probe is cleaved, resulting in an increase of fluorescence of the probe, it can be assessed whether or not the probe and the sample share the same amount of repeats. An array of probes is utilised, covering all possible alleles of the investigated STR-locus. The probes and method of the present invention are well-suited to be used in a portable, less-expensive DNA analysis device and can be applied in other fields than forensics, like food fraud, diagnostics and many others.Type: ApplicationFiled: March 1, 2021Publication date: April 20, 2023Inventors: Olivier Tytgat, Filip Van Nieuwerburgh, Dieter Deforce

Publication number: 20220340981Abstract: The disclosure relates to the field of DNA-fingerprinting, e.g., in a forensic setting. More specifically, the disclosure discloses a method to genotype polymorphisms such as short tandem repeats, relying on the fluorescein-quenching properties of guanine. As such, the degree of complementary between an amplified DNA sample and a specifically designed probe, can be assessed by measuring fluorescence intensity of the fluorophore attached to the probe upon hybridization or melting. The probes and method of the disclosure are well-suited to be used in a portable, less-expensive DNA analysis device and can be applied in other fields than forensics, like food fraud, diagnostics and many others.Type: ApplicationFiled: September 22, 2020Publication date: October 27, 2022Inventors: Olivier Tytgat, Filip Van Nieuwerburgh, Dieter Deforce, Senne Cornelis

Patent number: 9636417Abstract: The invention is based on the identification of aminopeptidase N (APN) as the receptor for F4 fimbriae of enterotoxigenic E. coli (ETEC). Based on the observation that oral administration of F4 fimbriae induces a protective intestinal mucosal immune response against a subsequent challenge with F4 ETEC, and the observation that the internalization of said F4fimbriae is clathrin-mediated, the present invention provides the characterization of APN as a target useful in: in an in vitro assay to screen for molecules that are capable to mimic the clathrin-mediated F4 endocytosis; in an in vitro assay to screen for molecules that are capable to modulate the binding of F4 fimbriae with APN; in the development of a carrier for the delivery of antigens/therapeutics, i.e. immunomodulators to the intestinal submucosa or the intestinal mucosa-associated lymphoid tissue, wherein said carrier comprises an APN specific target molecule that mimics the clathrin-mediated F4 endocytosis.Type: GrantFiled: January 15, 2015Date of Patent: May 2, 2017Assignee: Universiteit GentInventors: Kristien Rasschaert, Bruno Goddeeris, Eric Cox, Dieter Deforce

Publication number: 20070243561Abstract: Methods and compositions for detecting a form of chronic lymphocytic leukemia in a subject are described which allow for distinguishing more aggressive forms of the disease from less aggressive forms. Particularly described methods include assaying a sample obtained from the subject having or suspected of having chronic lymphocytic leukemia for a marker selected from a vimentin cleavage product, annexin 5 and 6-phosphogluconolactonase. A combination of any of these markers may be assayed in particular embodiments of a method according to the present invention. In particular embodiments, detection of an intermediate weight vimentin cleavage product is indicative of a less aggressive form of CLL associated with good prognosis.Type: ApplicationFiled: February 16, 2007Publication date: October 18, 2007Inventors: Ben Geeraerts, Laura Rassenti, Fritz Offner, Thomas Kipps, Dieter Deforce
