标题:High density immobilization of nucleic acids
发明人：O'DONNELL-MALONEY MARYANNE J; CANTOR CHARLES R; KOESTER HUBERT
权利人:SEQUENOM INC
摘要:Processes and kits for immobilizing a high density of nucleic acids on an insoluble surface, which are particularly useful for mass spectrometric detection of nucleic acids, are disclosed. Arrays containing the immobilized nucleic acids and use of the immobilized nucleic acids in a variety of solid phase nucleic acid chemistry applications, including nucleic acid synthesis (chemical and enzymatic), hybridization and/or extension, and sequencing, are provided. Serial and parallel dispensing tools that can deliver defined volumes of fluid to generate multi-element arrays of sample material on a substrate surface are further provided. Tools provided herein can include an assembly of vesicle elements, or pins, wherein each of the pins can include a narrow interior chamber suitable for holding nanoliter volumes of fluid. Methods for dispensing tools that can be employed to generate multi-element arrays of sample material on a substrate surface are also provided. The tool can dispense a spot of fluid to a substrate surface by spraying the fluid from the pin, contacting the substrate surface or forming a drop that touches against the substrate surface. The tool can form an array of sample material by dispensing sample material in a series of steps, while moving the pin to different locations above the substrate surface to form the sample array, The prepared sample arrays may be passed to a plate assembly that disposes the sample arrays for analysis by mass spectrometry.

摘要:This invention relates to Schiff's bases derived from amino acids and hydroxyaryl alkyl ketones, or a plant extract containing the same, having general chemical structure in FIG. 1 for topical application. This invention also relates to certain metal complex of said Schiff's bases, which have a crown-like appearance in their three-dimensional chemical structure, as in FIG. 2 . The Schiff's bases and their metal complexes of the present invention are useful for the modulation of metal-activated enzymes and metalloenzymes, such as Phenylalanine Hydroxylase, Tyrosine Transaminase, Phenylalanine Transaminase, Tyrosinase, various MMP (Matrix metalloproteases), Superoxide dismutase, 5-Alpha Reductase, and citrate lyase. These are further suitable for multifunctional topical methods for skin whitening, skin wrinkles reduction, skin antiaging, collagen synthesis, acne control, hair loss prevention, hair graying control, and facial oil control.
