Patent number: 8968677Abstract: An improved apparatus and method for dispersion of a labeling conjugate in a diagnostic assay, the result being a one-step assay. By eliminating a conjugate pad as in conventional lateral diagnostic devices, and forming a frazil ice pellicle (FIP), rehydration and flow are improved resulting in better reproducibility, improved sensitivity, and reduced costs of individual assay devices. The formation of a frazil ice film formed on a super cooled surface of a sample receiving means simplifies assay assembly. Lyophilization of the FIP improves the release of a sample/analyte/label matrix into a macro channel as in a direct flow assay, while at the same time allowing reagents to mix and flow, thereby optimizing the assay performance. The reagents of the conjugate and the formation of the FIP stabilize the conjugate proteins and provide extended shelf life to the diagnostic assay device.Type: GrantFiled: January 22, 2013Date of Patent: March 3, 2015Assignee: Quantum Design International, Inc.Inventors: Ronald T. LaBorde, Nicholas J. Neild

Patent number: 8969086Abstract: A sample processing system 101 that may be automated and methods are disclosed where sample(s) 198 are arranged on a carrier element 197 and a process operation control system 171 automatically processes the sample(s) perhaps robotically according to an desired aggregation of event dictated by an input 173. Alteration of an initial aggregated event topology may be accepted while the system is processing an initial aggregation and varied-parameter robotic control simulation functionalities 606 may be accomplished to determine an enhanced sequence for processing. Suggested operator actions may be displayed that might further enhance the scheduling of the altered aggregated event topology together with an automatic operator need prompt 608 that may inform an operator of a need for a particular action in order to accomplish the desired tasks.Type: GrantFiled: February 18, 2014Date of Patent: March 3, 2015Assignee: Dako Denmark A/SInventors: Marc Key, Gordon Feingold, Rosanne Welcher

Patent number: 8962341Abstract: An assay system designed to detect a protein biomarker in urine that is diagnostic for interstitial cystitis (IC). The presence of a 9 amino acid glycopeptide, antiproliferative factor (APF), in urine is unique to patients with IC. Urine samples from patients who exhibit symptoms consistent with IC are added to the assay system. Binding of APF to the cytoskeletal associated protein 4 (CKAP4) is positive for the presence of APF in urine and diagnostic for IC. The diagnostic system is a significant and surprising advance in diagnosis of IC and has commercial applications relevant to women and men who suffer from symptoms consistent with IC.Type: GrantFiled: December 10, 2009Date of Patent: February 24, 2015Assignees: The Commonwealth Medical College, University of Florida Research Foundation, Inc.Inventors: David Alan Zacharias, Sonia Lobo Planey
