摘要:
A device and method useable for fast processing and depositing of biomolecules. The method includes the following steps: receiving a first set of analytes to be analysed; passing in an array format, analytes through extraction means where said biomolecules adhere to solid phase means; washing said solid phase means with a washing liquid, leaving only said biomolecules; performing elution by passing portions of organic solvent through each said solid phase, forming eluates constituting a second set of analytes containing said biomolecules, as a result of said elution; dispensing, in an array format, said second set of analytes using a micro dispensing array; controlling said array to dispense precise amounts of each one of said second set of analytes on target areas of a target plate.

A processing module for extracting certain biomolecules from a solution, comprising an extraction unit having at least one elongated channel (101) each of said at least sine channel have un inlet (102) and an outlet (103) and being provided with adhering units (201), each said unit being provided with adhesive means, having affinity for said certain biomolecules, said extraction unit further comprises docking means (205) having an inlet array and an outlet array, that enables the extractor to be docked to and undocked from other devices having corresponding docking means, such that said solution or another fluid can be made to flow from said other devices, entering the inlet array, to flow through the at least one channels(101) and to leave the extraction device via the outlet array.
摘要:
The invention relates to a method and a machine for biomolecule handling using an array dispenser. More particularly, the invention relates to a method and a machine in which one or two separation procedures are performed in parallel channels and the separated biomolecules are deposited on a two-dimensional target plate for analysis e.g. in a MALDI TOF MS device (Matrix Assisted Laser Desorption/Ionisation Time-of-Flight Mass Spectrometry). A method of sample handling comprises the following steps: supplying (101) a number of samples to a multichannel separation device having an equal number of separation channels; separating (102) the samples in parallel in said number of separation channels; supplying said channels to an array dispenser after separation; dispensing (103) said channels in parallel on to a target plate maintaining the separation of the multichannel separation device.
摘要:
A plate suitable for use with mass spectrometers comprising a number of target spots arranged in a surface portion of said plate making it possible to deposit small amounts of fluid at said target spots without the fluid escaping or getting mixed with fluid deposited at another target surface of the same plate. The target surfaces being arranged in a surface portion of said plate so that a base material of said plate constitutes the walls of receptacles, characterised in that the shape, size, temperature and possible agents of said receptacle facilitate evaporation of a solution in which sample molecules are suspended. Embodiments include different types of matrix and enzymes arranged at said spots, and methods for enhancing MALDI analysis efficiency.
摘要:
Methods for producing and using protein/peptide fingerprints, derived from elastin degraded by the enzyme human Neutrophil Elastase (HNE), allowing identification and investigation of disease-associated proteins/peptides that can be linked to specific drug targets, or to specific drug target combinations. The methods are particularly useful for studies relating to Chronic Obstructive Pulmonary Disease (COPD).

摘要:
A method of selecting and identifying bio-molecules present in a bio-sample is disclosed. The method comprises the steps of: obtaining a bio-sample; amplifying (2) the bio-molecules present in the bio-sample to improve the case of detection of said bio-molecules; separating the bio-molecules in said amplified bio-sample; depositing (3) the amplified bio-molecules on to a suitable media. Detecting means are then used to identify or detect the presence of bio-molecules in said amplified and separated sample wherein said amplification step occurs in close physical proximity to said deposition step. A device (1) for carrying out the method is also disclosed as is a protein chip library produced by the device or method.
摘要:
A dispensing device for use in chemical analysis comprising at least two dispenser nozzles, a chamber having at least two inlets, a membrane entity constituting part of defining elements of said chamber, said membrane entity comprising at least one flexible membrane, and an actuation element, such that liquids brought to flow through said inlets into said chamber can be pressurised by actuating the membrane entity by providing a pulse to said actuation element, and thereby dispensing an amount of liquid through each of said at least two nozzles. Embodiments include devices comprising integrated free flow electrophoresis separation means.
摘要:
The invention relates to devices and methods for chemical analysis, specifically to devices for extracting molecules, e.g. biomolecules such as peptides, and/or proteins, from a mixture of molecules in a solution and performing sample treatment on the extracted molecules before presenting them to an analysis instrument. The method for analysis of samples uses a combined sample treatment and sample carrier device. Said device comprises a plate with inlets at one side connected to respective compartments situated at respective array positions for receiving samples to be treated and analysed, each compartment being in communication with an outlet enabling fluid flow through the plate. The method comprises the steps of supplying an external container with a sample; optionally, subjecting the sample to a first treatment in the external container; transferring the sample to the combined sample treatment and sample carrier device; and subjecting the sample to a second treatment exploiting fluid flow through the device, wherein a medium is trapped in the device.
