摘要:
The invention provides a method for analyzing a material, comprising:
providing a vesicle suitable for carrying a fluid having said material therein, disposing said vesicle adjacent a first location of a surface of a substrate, controlling said vesicle to deliver a nanoliter volume of the fluid to provide a defined and controlled volume of said fluid at said first location of said surface of the substrate, moving said vesicle to a second position adjacent a second location on said surface of the substrate to dispense a defined and controlled volume of said material along an array of locations on said substrate surface, and performing mass spectrometry analysis for said material at each location of said array.
摘要:
A process for determining the identity of a target polypeptide using mass spectroscopy is provided. Depending on the target polypeptide to be identified, a process as disclosed can be used, for example, to diagnose a genetic disease or chromosomal abnormality, a predisposition to a disease or condition, or infection by a pathogenic organism; or for determining identity or heredity.
摘要:
Fast and highly accurate mass spectrometry-based processes for detecting a particular nucleic acid sequence in a biological sample are provided. Depending on the sequence to be detected, the processed can be used, for example, to diagnose a genetic disease or chromosomal abnormality; a predisposition to a disease or condition, infection by a pathogenic organism, or for determining identity or heredity. A method and apparatus for creating multiple branch wells from a parent well is disclosed. A multiple branching sub is provided for placement at a branching node of a well. Such sub includes a branching chamber and a plurality of branching outlet members. The outlet members during construction of the branching sub, have previously been distorted into oblong shapes so that all of the branching outlet members fit within an imaginary cylinder which is coaxial with and substantially the same radius as the branching chamber. After deployment of the branching sub via a parent casing in the well, a forming tool is lowered to the interior of the sub. The outlet members are extended outwardly by the forming tool and simultaneously formed into substantially round tubes. Next, each outlet member is plugged with cement, after which each branch well is drilled through a respective outlet member. If desired, each branch may be lined with casing and sealed to a branching outlet by means of a casing hanger. A manifold placed in the branching chamber controls the production of each branch well to the parent well.

摘要:
The invention provides a dispensing apparatus for dispensing nanovolumes of fluid in chemical or biological procedures onto the surface of a substrate, comprising:
a housing having a plurality of sides and a bottom portion having formed therein a plurality of apertures, said sides and bottom portion of said housing defining an interior volume, one or more fluid transmitting vesicles, mounted within said apertures, having a nanovolume sized fluid holding chamber for holding nanovolumes of fluid, said fluid holding chamber being disposed in fluid communication with said interior volume of said housing, and dispensing means in communication with said interior volume of said housing for selectively dispensing nanovolumes of fluid from said nanovolume sized fluid transmitting vesicles when the fluid is loaded with said fluid holding chambers of said vesicles, whereby said dispensing means dispenses nanovolumes of the fluid onto the surface of the substrate when the apparatus is disposed over and in registration with the substrate.
