Patent number: 11927595Abstract: Disclosed is the invention to conduct immuno-adsorption of free 25(OH) vitamin D from blood or blood components, notably serum or plasma, after which the absorbed material is measured. A fluoro-alkyl surfactant is used to enhance the solubility of Vitamin D and allow the measurement of free Vitamin D2. The invention thus employs a binding protein to absorb the free 25(OH) vitamin D. Thereafter the binding protein comprising the 25-OH vitamin D is subjected to a competitive binding assay with a labeled vitamin D compound, preferably radiolabeled, fluorescent labeled, luminescent labeled, biotin labeled, gold labeled or enzyme labeled. Alternatively the immunocaptured 25-OH vitamin D can be quantitated by mass spectrometry.Type: GrantFiled: January 15, 2021Date of Patent: March 12, 2024Assignee: FUTURE DIAGNOSTICS B.V.Inventors: Michaël Franciscus Wilhelmus Cornelis Martens, George Henry Parsons, Franciscus Maria Anna Rosmalen, Leon Maria Jacobus Wilhelmus Swinkels

Patent number: 11493507Abstract: An immunoassay for the detection of an analyte in a sample includes a plurality of moieties capable of binding to the analyte. Capture moieties, which are not specific for the same epitope, are bound to a solid substrate, and at least one epitope-specific detection moiety is bound to a detectable marker. The detectable marker is a large particle marker having a particle size of ?50 nm and ?5000 nm.Type: GrantFiled: September 7, 2010Date of Patent: November 8, 2022Assignee: Siemens Healthineers Nederland B.V.Inventors: Wendy Uyen Dittmer, Toon Hendrik Evers, Marco Hendrikus Hefti, David Walterus Cornelis Dekkers, Michael Franciscus Wilhelmus Cornelis Martens

Patent number: 10422805Abstract: Disclosed is an invention in the field of conducting an immunoassay of 25(OH) vitamin D in blood or blood components, notably serum or plasma. The invention employs a perfluoro alkyl acid, or a salt thereof, to release 25(OH) vitamin D from vitamin D binding protein. Thereafter the binding protein comprising the 25-OH vitamin D is subjected to a competitive binding assay with a labeled vitamin D compound.Type: GrantFiled: December 27, 2011Date of Patent: September 24, 2019Assignee: FUTURE DIAGNOSTICS B.V.Inventors: Leon Maria Jacobus Wilhelmus Swinkels, Antonius Franciscus Maas, Michael Franciscus Wilhelmus Cornelis Martens
