摘要: Methods of analysing peptides by mass spectrometry are disclosed. In particular, methods of analysing peptides by fragmentation mass spectrometry (MSn, where n is at least 2) are disclosed. The methods involve derivatisation of a peptide at its N-terminus such that peaks corresponding to both a and b (and y) daughter ions are identifiable in fragmentation mass spectra of the derivatised peptide. The fragmentation mass spectra of the derivatised peptide contain additional information (relative to the fragmentation mass spectra of the underivatised peptide) useful for determination of the amino acid sequence of the peptide.

摘要: A reagent comprises: a) an analyte moiety comprising at least two analyte residues, and linked to; b) a tag moiety comprising one or more reporter groups adapted for detection by mass spectrometry, wherein a reporter group designates analyte residue, and the reporter group at each position of the tag moiety is chosen to designate an analyte residue at a defined position of the analyte moiety. A plurality of such reagents, each comprising a different analyte moiety, provides a library of reagents which may be used in assay methods involving a target substance. Analysis of the tag moieties indicates the nature of the analyte moieties bound to the target substance. A method of sequencing nucleic acid employs a library of the reagents to determine the sequence of a target nucleic acid.

摘要: A device for individually analysing cells of interest, comprising (a) a channel for receiving the contents of a cell of interest, wherein the channel has an input end and an output end, and (b) a cell trapping site in proximity to the input end of the channel, wherein (i) the input end of the channel is adapted such that an intact cell of interest cannot enter the channel; and (ii) the channel contains one or more analytical components for analysing the contents of the cell of interest. In use, a cell is applied to the device, where it is trapped by the cell trapping means. The cell cannot enter the channel intact, but its contents can be released in situ to enter the channel's input end. The contents can then move down the channel, towards the output end, and they encounter the immobilised reagents, thereby permitting analysis of the cell contents.

摘要: A method of making a set of labelled compounds by the use of a preferably particulate support, comprises dividing the support into lots, performing a different chemical reaction on each lot of the support, e.g. to couple a chemical moiety to that lot of the support, tagging a fraction of each lot of the support with a different label, and combining the said lots of the support. The steps are repeated several times, preferably to build up oligomer molecules carrying labels which identify the nature and position of a monomer unit of the oligomer, and which are releasable from the support. Preferred labels, which are releasable from the compounds by cleavage to provide charged groups for analysis by mass spectrometry, are groups of the trityl (trimethylphenyl) family. Also claimed are libraries of these labels is and their use in assays and nucleic acid analysis methods.

摘要: A method of electrochemically patterning a surface comprises providing an electrolyte overlying the surface and an array of electrodes adjacent the surface and in contact with the electrolyte, and altering the potential of one or more electrodes of the array so as to deposit or remove or chemically modify a substance on the surface adjacent the electrode. Several such treatments can be performed in sequence, using different electrodes of the array. The method is particularly suitable for step-wise chemical synthesis e.g. of oligonucleotides or other oligomers tethered to the surface. Electrode arrays for use in the method are also claimed.
