    摘要: Provided is a method for characterising a polypeptide or a population of polypeptides, which method comprises the steps of:

    (a) contacting a sample comprising one or more polypeptides with a lysine reactive agent to cap ε-amino groups;
    (b) optionally reacting the sample of polypeptides with an amine reactive reagent to block α-amino groups;
    (c) digesting the sample of polypeptides with a sequence specific cleavage reagent to produce peptide fragments;
    (d) optionally deactivating the cleavage reagent;
    (e) removing those peptides having uncapped or unblocked amino groups; and
    (f) recovering the N-terminal peptides.

    摘要: A method for characterising polypeptides, which comprises: (a) treating a sample comprising a population of one or more polypeptides with a cleavage agent which is known to recognise in polypeptide chains a specific amino acid residue or sequence and to cleave at a cleavage site, whereby the population is cleaved to generate peptide fragments; (b) isolating a population of the peptide fragments which bear at one end a reference terminus comprising either only an C-terminus or only an N-terminus and which bear at the other end the cleavage site proximal to the reference terminus; and (c) determining a signature sequence of at least some of the isolated framents, which signature sequence is the sequence of a predetermined number of amino acid residues running from the cleavage site; wherein the signature sequence and the relative position of the cleavage site to the reference terminus characterise the or each polypeptide.

    摘要: Provided is a method for characterising a polypeptide or a population of polypeptides, which method comprises the steps of:

    (a) Optionally reducing disulphide linkages in the polypeptides, if they are present, and capping free thiols in the polypeptides, if they are present;
    (b) contacting a sample comprising one or more polypeptides with a sequence specific cleavage reagent which cleaves one or more polypeptides on the C-terminal side of a lysine residue to produce peptide fragments;
    (c) optionally deactivating the cleavage reagent;
    (d) contacting the sample with a lysine reactive agent to cap ε-amino groups;
    (e) removing those peptides having capped ε-amino groups; and
    (f) recovering the C-terminal peptides

    摘要: Provided is a method for characterising one or more nucleic acids, which method comprises immobilising double-stranded nucleic acids on a solid phase support, cleaving the immobilised nucleic acids with an endonuclease such that each cleaved nucleic acid has a double-stranded portion, denaturing the cleaved nucleic acids to form single-stranded cleaved nucleic acid, hybridising one or more oligonucleotide sequences to the resulting single-stranded cleaved nucleic acid, each oligonucleotide sequence comprising a pre-determined recognition sequence situated such that it recognises a sequence which was part of the double-stranded portion of the nucleic acid and a label specific to the recognition sequence, extending correctly hybridised oligonucleotide sequences along the single-stranded portion of the immobilised nucleic acid to form an extended strand, denaturing the extended strand from the immobilised strand and characterising the immobilised nucleic acid by identifying the size of the extended strand and the identity of the recognition sequence.

    摘要: Provided is a method for characterising a polypeptide or a population of polypeptides, which method comprises: (a) contacting a sample comprising one or more polypeptides with a first cleavage agent to generate polypeptide fragments; (b) isolating one or more polypeptides fragments, each fragment comprising the N-terminus or the C-terminus of the polypeptide from which it was fragmented; (c) identifying the isolated fragments by mass spectrometry; (d) repeating steps (a)-(c) on the sample using a second cleavage agent that cleaves at a different site from the first cleavage agent; and (e) characterising the one or more polypeptides in the sample from the fragments identified in steps (c) and (d).
