    摘要: The present invention is related to a method for selecting a treatment for a human patient suffering from cancer, comprising:
    measuring by mass spectrometry the amount of an IRS1 fragment peptide in a protein digest prepared from a sample of formalin fixed tumor tissue from the patient and, optionally, calculating the level of IRS1 protein in said sample; and selecting a treatment based on the presence, absence, or amount of said IRS1 fragment peptide or the level of IRS1 protein in said sample, wherein the IRS1 fragment peptide is SEQ ID NO:70 or SEQ ID NO:76.

    摘要: The application relates to an electrode for use in the electrochemical detection of target species, and in particular for the detection of insulin. The application enables insulin to be detected with high selectivity and with a detection limit in the picomolar range or lower. The electrodes of the invention can easily be reused and are ideally suited for use in point-of-care diagnostics. In a preferred embodiment, the electrode comprises an antibody modified, polyethylene glycol (PEG) monolayer assembled on a gold surface. In a second embodiment, the electrode comprises a chemisorbed zwitterionic carboxybetaine polymer obtained by photopolymerisation of carboxybetaine methacrylate (CBMA). This allows the use of non Faradaic analysis to determine the insulin concentration even in undiluted blood serum.
