| 20110268610 | Tip Tray Assembly For Optical Sensors - An apparatus and method for packaging of an optical sensing fiber is disclosed. The apparatus includes a substrate with a plurality of openings, and each opening is configured for holding an optical sensing assembly. The assembly is positioned in the opening with a tip of the assembly extending through the opening to be suspended from the substrate. In addition, openings are arranged so the assembly positioned therein avoids contacting another assembly positioned therein. The apparatus can include a support member for supporting the substrate and positioning the substrate so the tip of the assembly suspended from the opening in the substrate contacts solution in one of a plurality of wells in a container adjacent to the substrate. The assembly can be configured for preparing of the optical assembly for assay. An agitation assembly for agitating the container to create flow of the solution in the container wells over an optical sensing assembly is also disclosed. | 11-03-2011 |
| 20110236911 | Precipitating Substrate for Bio-Layer Interferometry - Improved apparatus, compositions, and methods for carrying out interferometry-based assays for detecting analytes in a sample through the use of a precipitating substrate to enhance an interferometry binding signal, and kits useful for carrying out these assays. Methods comprise providing an optical assembly comprising an optical element with a transparent material and adapted for coupling to a light source via a fiber, a first reflective surface and a second reflecting surface having a first analyte-binding molecule and separated from said first surface by a distance, d, exposing said optical element to a sample comprising said analyte, a second analyte binding molecule, and a precipitating substrate; and detecting a change in thickness at said first reflective surface thereby detecting said analyte in said sample. Kits include reagents for derivatizing assay components along with packaging and instructions for use. | 09-29-2011 |

| 20100238453 | Fiber-Optic Assay Apparatus Based On Phase-Shift Interferometry - Apparatus and method for detecting the presence or amount or rate of binding of an analyte in a sample solution is disclosed. The apparatus includes an optical assembly having first and second reflecting surfaces separated by a distance “d” greater than 50 nm, where the first surface is formed by a layer of analyte-binding molecules, and a light source for directing a beam of light onto said first and second reflecting surface. A detector in the apparatus operates to detect a change in the thickness of the first reflecting layer resulting from binding of analyte to the analyte-binding molecules, when the assembly is placed in the solution of analyte, by detecting a shift in phase of light waves reflected from the first and second surfaces. | 09-23-2010 |
| 20100093106 | Amine-Reactive Biosensor - Described are methods, articles of manufacture, and kits for coupling an analyte-binding molecule to the surface of a biosensor through formation of amide bonds. One amide bond is formed between a first carboxyl group on a polymer and a first reflecting surface comprising an aminoalkyl moiety. A second amide bond is formed between a second carboxyl group on the polymer and an amine group on an analyte-binding molecule to be coupled. The present invention thus provides for covalent attachment of the analyte-binding molecule to the biosensor, thus providing advantages over non-covalent attachment methods of the prior art. These advantages include the ability to couple without using bio tin (which, in some instances can alter functional properties of a molecule) the ability to improve the fidelity with which a binding or dissociation reaction that takes place on the surface of the biosensor represents a solution phase reaction, and the ability to regenerate the sensor by stripping ligands from the covalently bound analyte-binding molecule. | 04-15-2010 |
| 20090068694 | Enzyme Activity Measurements Using Bio-Layer Interferometry - Disclosed are enzyme assays using biolayer interferometry. Assays may be carried out using immobilized substrate or with a substrate capture format. In certain embodiments, the assays are carried out using unlabeled substrates. The methods are broadly applicable to enzyme assay measurements, can be carried out in vivo or in vitro, and are easily multiplexed. | 03-12-2009 |
