The invention relates to a method of diagnosis of colorectal cancer in a diagnostic sample of a valid body tissue taken from a human subject, which comprises detecting an increased concentration of a protein in the diagnostic sample, compared with a control, normal human sample, the protein being: transforming growth factor-beta induced protein IG-H3 (SwissProt Acc. No. Q15582); suppressor of G2 allele of SKP1 homolog (isoform 2) (SwissProt Acc. No. Q9Y2Z0-2); hypothetical protein (part of URG4) (SwissProt Acc. No. Q9NWR7); calponin-2 (SwissProt Acc. No. Q99439); heat shock protein HSP90-beta (SwissProt Acc. No. P08238); phosphoglycerate mutase 1 (SwissProt Acc. No. P18669); serpin C1 protein (SwissProt Acc. No. P01008); or haptoglobin precursor (SwissProt Acc. No. P00738); or a decreased concentration of a protein in the diagnostic sample, compared with a control, normal human sample, the protein being serotransferrin (SwissProt Acc. No. P02787); 26S proteasome subunit p40.5 (Swiss Prot Acc. No. Q9UNM7); aldo-keto reductase family 1 member B10 (SwissProt Acc. No. O60218); fructosamine-3-kinase (SwissProt Acc. No. Q9H479); peripherin (SwissProt Acc. No. P41219); alpha-2-macroglobulin (SwissProt Acc. No. P01023); serpin C1 protein (SwissProt Acc. No. P01008); or apolipoprotein A IV (SwissProt Acc. No. P06727). The same proteins can be used for prognosis by detecting changes in their concentration in the course of treatment for colorectal cancer.

A mass label for labelling and detecting a biological molecule by mass spectroscopy, which label comprises the following structure: X-L-M wherein X is a mass marker moiety comprising the following group: formula (I), wherein the cyclic unit is aromatic or aliphatic and comprises from 0-3 double bonds independently between any two adjacent atoms; each Z is independently N, N(R), C(R), CO, CO(R), C(R), O or S; X is N, C or C(R); each Ris independently H, a substituted or unsubstituted straight or branched C-Calkyl group, a substituted or unsubstituted aliphatic cyclic group, a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group; and y is an integer from 0-10, L is a cleavable linker comprising an amide bond and M is a mass normalization moiety. 

Reactive mass labels

Provided is a method for characterizing a molecule by mass spectrometry, which molecule comprises one or more free amino groups, which method comprises: (a) reacting one or more free amino groups in the molecule with a mass tag reagent comprising a reactive functionality capable of reacting with an amino group, and a tertiary amino group linked to the reactive functionality; and (b) characterizing the molecule by mass spectrometry.

Labeling agents for mass spectrometry comprising tertiary amines

Methods and compositions relating to Alzheimer's disease are provided. Specifically, proteins that are differentially expressed in the Alzheimer's disease state relative to their expression in the normal state are provided. Proteins associated with Alzheimer's disease are identified and described. Methods of diagnosis of Alzheimer's disease using the differentially expressed proteins are also provided, as are methods for the identification and therapeutic use of compounds for the prevention and treatment of Alzheimer's disease.
