    摘要: A screening system and method are described herein which provide a unique and practical solution for enabling label-free high throughput screening (HTS) to aid in the discovery of new drugs. In one embodiment, the screening system enables direct binding assays to be performed in which a biomolecular interaction of a chemical compound (drug candidate) with a biomolecule (therapeutic target) can be detected using assay volumes and concentrations that are compatible with the current practices of HTS in the pharmaceutical industry. The screening system also enables the detection of bio-chemical interactions that occur in the wells of a microplate which incorporates biosensors and surface chemistry to immobilize the therapeutic target at the surface of the biosensors. The screening system also includes fluid handling and plate handling devices to help perform automated HTS assays.

    摘要: The present invention provides a method for preparing a physically stable array of biological membranes, including membrane proteins, on a surface, and the resultant article of manufacture. The method comprises providing a substrate; creating either a polar surface or reactive surface by coating the substrate with a material that either: (1) enhances the stability of lipid spots during withdrawing through a water/air interface and washing and drying protocols; or (2) gives rise to minimal non-specific binding of a labeled target to a background surface, and high specific binding to a probe receptor in said membrane array, or (3) both; and depositing an array of biological-membrane microspots on the substrate. The method may further comprise applying a reagent that includes a soluable protein to stabilize the biological membranes on the surface. Also provided is an article having biological-membrane microspots that are associated in a stable fashion with a substrate surface embodying these properties.

    摘要: An optical reader system is described herein that uses a scanned optical beam to interrogate a biosensor to determine if a biomolecular binding event occurred on a surface of the biosensor. In one embodiment, the optical reader system includes a light source, a detector and a processor (e.g., computer, DSP). The light source outputs an optical beam which is scanned across a moving biosensor and while this is happening the detector collects the optical beam which is reflected from the biosensor. The computer processes the collected optical beam and records the resulting raw spectral or angle data which is a function of a position (and possibly time) on the biosensor. The processor can then analyze the raw data to create a spatial map of resonant wavelength (peak position) or resonant angle which indicates whether or not a biomolecular binding event occurred on the biosensor. Several other uses of the raw data are also described herein.
