Abstract: The present invention relates to the use of mass spectrometry to analyze arrays. The present invention provides methods for characterizing solutions comprising one or more proteins using arrays and mass spectrometry. The arrays of the present invention are coated with porous gold and utilize hydrophobic and hydrophilic self-assembled monolayers.

Abstract: A tandem mass spectrometer includes a linear time-of-flight mass analyzer and curved field reflectron mass analyzer. The curved-field reflectron mass analyzer is disposed at an end of the linear time-of-flight mass analyzer such that ions having a plurality of ion masses formed in the linear time-of-flight analyzer such that ions having a plurality of ion masses formed in the linear time-of-flight analyzer enter the curved-field reflectron mass analyzer. The tandem mass spectrometer also includes a mass selection gate disposed between the time-of-flight mass analyzer and the curved-field reflectron mass analyzer. The mass selection gate selects an ion mass from the plurality of ion masses. Furthermore, the tandem mass spectrometer also includes a dissociating component located in a path of the ions formed in the linear time-of-flight analyzer. The dissociating component causes dissociation of the ions into a plurality of ion fragments.

Abstract: A point-of-care mass spectrometer system has a sampling system, an ionization component structured to receive a sample for analysis from the sampling system, a mass analyzer structured to receive a source of ions for analysis from the ionization component, and a detector structured to detect ions from the mass analyzer and to generate an output signal. The sampling system selects a subset of peptides from a sample by immunopurification of multiple histocompatability complexes and concentrates the subset of peptides to provide the sample to the ionization component.

Abstract: Provided are diagnostic and therapeutic methods of treating sarcoidosis comprising the use of microbial catalase-peroxidase protein, its peptide fragments, or derivatives thereof.

Abstract: A time-of-flight mass spectrometer which has an iron source, an evacuated tube proximate the ion source and adapted to receive ions from the ion source, and a detector disposed at an end of the evacuated tube opposite an end proximate the ion source. The ion source is constructed to generate an electric field that changes non-linearly as a function of position along a path from the ion source to the detector. The ion source is constructed to generate an electric field that changes as a function of time, the electric field being provided to accelerate ions from the ion source to the detector.

Abstract: A polymer blend and a golf ball employing a cover formed of that polymer blend are disclosed. The polymer blend is made from about 5 to about 95 phr of the polymer blend. About 5 to about 95 phr resin is included in the blend. The ball that employs the cover of the polymer blend has excellent click and feel, as well as excellent spin characteristics.

Abstract: Sulfur dioxide can be adsorbed from gas mixtures using cross-linked, water-insoluble polymers of N-glycidylpiperazine or N-glycidyl polyalkylpiperazines as the adsorbents.
