This Is Measured By A Human Jury,Subject To Numerous Factors Of Variation. Gray Level Intensities Were Obtained For The Apex,The Center,And The Basal Parts Of Each Chip Using Image Analysis Of Frying Assays. We Then Tested A Feed Forward Artificial Neural Network Designed To Associate These Data With Color Categories. It Behaved In Good Agreement With Human Estimations,Obtaining Correlation Coefficients Of 0.972 For Training Data And Of 0.899 For Validation Data. A Systematic Study Of The Response Of The Model Allowed Understanding The Criteria Of Evaluation Used By The Human Operators. DOI:10.1111/j.1365-2621.2003.Tb05757.X

专利号:US-6770436-B1 优先权日:1996-11-14 标题:Chemical amplification for the synthesis of patterned arrays 发明人:BEECHER JODY E; GOLDBERG MARTIN J; MCGALL GLENN H 权利人:AFFYMETRIX INC 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.
专利号:US-9376461-B2 优先权日:2011-06-06 标 题:Non-enzymatic synthesis of O-acetyl-ADP-ribose and analogues thereof 发明人:KOPPETSCH KARSTEN; SZCZEPANKIEWICZ BRUCE G; PERNI ROBERT B 权利人:KOPPETSCH KARSTEN; SZCZEPANKIEWICZ BRUCE G; PERNI ROBERT B; GLAXOSMITHKLINE LLC 摘要:Provided herein is a simple, one-step, non-enzymatic synthesis of O-Acetyl-ADP-ribose (OAADPR) from NAD and sodium acetate in acetic acid. The extension of this reaction to other carboxylic acids, demonstrates that the reaction between NAD, and NAD analogs produces mixtures of the corresponding 2′- and 3′-carboxylic esters. Included are O-carboxyl-ADP-ribose compounds and corresponding methods of synthesis (e.g., O-propionyl-ADP-ribose, O-succinyl-ADP-ribose, O-malonyl-ADP-ribose), as well as non-adenosine nucleoside compounds.
