    Abstract: Compounds, compositions, methods for sequencing proteins and peptides, and methods for identifying proteins and peptides in a mixture, are disclosed. Compounds of formula A-B-C wherein A is a nucleophilic reactive group, B is a detectable moiety capable of being isotopically labeled, and C is a charge replacement group, are used to label the peptides at the N-terminus or the C-terminus. The tagged peptides can then be analyzed by mass spectroscopy.

    Abstract: The invention in particular embodiments provides an evanescent wave sensor which includes a ligand bound to a sensor substrate via a NCYX linker moiety, as defined herein. Methods of making the subject evanescent wave sensors are also provided which include contacting a first reactive moiety which has an isocyanato (or isothiocyanato) moiety with a second reactive moiety which has an hydroxyl, thiol, or amino moiety, as further described herein. Also provided by the invention are methods in which a subject evanescent wave sensor is contacted with a sample, and binding of analytes in the sample to the sensor is assessed by evanescent wave detection. The invention also provides kits and systems for performing the subject methods.

    Abstract: A method useful in the analysis of glycosylated proteins, in which a mixture containing glycosylated proteins and unglycosylated proteins is contacted with a resin that includes a nucleophile bound to a solid support via a linker. The contacting is performed under conditions sufficient to result in removal of the glycosyl group from the glycosylated proteins and to concomitantly result in the deglycosylated proteins covalently bound to the solid support. The deglycosylated proteins bound to the solid support may be rinsed to remove proteins that are not covalently bound to the solid support. The deglycosylated proteins are released from the solid support and may be subjected to further purification and/or analysis.
