摘要:
The present invention provides an array of polymers and methods of forming arrays of polymers by providing a substrate having a first layer including one or more dielectric coatings on a solid support and a second layer including a plurality of polymers disposed on the first layer. The invention also provides methods for forming an array of polymers on a substrate using light-directed synthesis by providing a substrate having a first layer including one or more dielectric coatings on a solid support; derivatizing the first layer by contacting the first layer with a silanation reagent, and a second layer disposed on said first layer wherein the second layer includes functional groups protected with a photolabile protecting group.
摘要:
A method and apparatus for imaging a sample are provided. An electromagnetic radiation source generates excitation radiation which is sized by excitation optics to a line. The line is directed at a sample resting on a support and excites a plurality of regions on the sample. Collection optics collect response radiation reflected from the sample I and image the reflected radiation. A detector senses the reflected radiation and is positioned to permit discrimination between radiation reflected from a certain focal plane in the sample and certain other planes within the sample.

Methods and systems for performing analytical reactions under reduced or non-oxygen conditions, where such reactions are potentially subject to damaging effects of oxygen, including particularly fluorescent based detection methods where fluorescent species may be prone to generation of reactive oxygen species.
摘要:
Radiation-activated catalysts (RACs), autocatalytic reactions, and protective groups are employed to achieve a highly sensitive, high resolution, radiation directed combinatorial synthesis of pattern arrays of diverse polymers When irradiated, RACs produce catalysts that can react with enhancers, such as those involved in autocatalytic reactions The autocatalytic reactions produce at least one product that removes protecting groups from synthesis intermediates This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers
摘要:
Labeled targets on a support synthesized with polymer sequences at known locations according to the methods disclosed in U.S. Pat. No. 5,143,854 and PCT WO 92/10092 or others, can be detected by exposing selected regions of sample 1500 to radiation from a source 1100 and detecting the emission therefrom, and repeating the steps of exposition and detection until the sample is completely examined.
