摘要： Methods and apparatus, including computer program products, implementing and using techniques for collecting optical data pertaining to one or more characteristics of a sample. The apparatus has a light source, one or more illumination optical elements, a scanner, one or more collection optical elements, and a device forming an aperture that limits detection of light from the sample. The illumination optical elements direct a light beam from the light source onto the sample. The scanner scans the light beam across the sample. The collection optical elements collect light from the sample and transmit the collected light to a detector. None of the collection optical elements are included among the illumination optical elements. The device forming an aperture limits detection of light from the sample to light associated with a limited vertical depth within the sample, and is one of the collection optical elements.

摘要： Methods and apparatus for assaying biological materials employ multi-well substrates as described herein. The substrates include a plurality of wells, typically each of several nanoliters volume or smaller having consistent dimensions and formed in a rigid substrate such as a glass disk. Each well may be provided with a circumferential lip to minimize crosstalk between wells and/or facilitate optical location of the individual wells during interrogation. Samples are provided to the individual wells and assayed by an optical technique employing fluorescence, polarization, reflectance, or the like. A scanning laser system may be employed for this purpose. The substrate may rotate during the scan to allow consistent interrogation of the wells without stopping and starting the rotation. Multiple rotations may also be employed repeatedly interrogate the samples for use in a kinetic study, for example.

摘要： Methods and apparatus are described for detecting specific binding between first and second chemical entities. The first chemical entity in association with a first fluorophore is immobilized. The second chemical entity is allowed to bind with the immobilized first chemical entity. The second chemical entity is or becomes coupled to a second fluorophore, which forms a FRET pair with the first fluorophore. The bound chemical entities are exposed to radiation at an excitation frequency for either the first or the second fluorophore, and polarization anisotropy of a FRET fluorescent signal from the bound chemical entities is measured to detect specific binding between the first and second chemical entities. Techniques are also disclosed for detecting whether a FRET interaction is occurring between a first chemical entity including a donor fluorophore and a second chemical entity including an acceptor fluorophore, using simultaneous anisotropy measurements at the wavelengths of the donor and acceptor fluorophores.

Each sample well is configured to hold a sample solution containing objects that are to be characterized based on their light scattering properties. One or more sample solutions are dispensed into the sample wells. A specular reflection reducing element is applied to at least some of the sample solutions in the sample wells to decrease reflections of light into one or more detectors. A light beam is directed from a light source onto the objects in the sample wells. Light scattered by the objects in the sample wells is collected and transmitted to one or more detectors. The signal from the detectors is analyzed to detect the one or more characteristics of the one or more samples.
