20090197284 | Analysis of Proteins from Biological Fluids Using Mass Spectrometric Immunoassay - Presented herein are methods, devices and kits for the mass spectrometric immunoassay (MSIA) of proteins present in complex biological fluids or extracts. Pipettor tips containing porous solid supports that are covalently derivatized with affinity ligand and used to extract specific proteins and their variants from various biological fluids. Nonspecifically bound compounds are rinsed from the extraction devices using a series of buffer and water rinses, after which the wild type protein (and/or its variants) are eluted directly onto a target in preparation for analysis such as matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Mass spectrometry of the eluted sample then follows with the retained proteins identified via accurate molecular mass determination. Protein and variant levels can be determined using quantitative methods in which the protein/variant signals are normalized to signals of internal reference standard species (either doped into the samples prior to the MSIA analysis, or other endogenous protein co-extracted with the target proteins) and the values compared to a working curves constructed from samples containing known concentrations of the protein or variants. Such MSIA devices, kits and methods have significant application in the fields of; basic research and development, proteomics, protein structural characterization, drug discovery, drug-target discovery, therapeutic monitoring, clinical monitoring and diagnostics, as well as in the high throughput screening of large populations to establish and recognize protein/variant patterns that are able to differentiate healthy from diseased states. | 08-06-2009 |
20090209047 | BIOMARKERS AND ASSAYS FOR MYOCARDIAL INFARCTION - Presented herein are novel blood plasma/serum biomarkers related to cardiovascular disease. These newly identified biomarkers create the basis for multiple (single) assays using traditional bioassay technologies and when used in combination yield exceptional clinical sensitivity and specificity in the determination of myocardial infarction (MI). A multiplexed, mass spectrometric immunoassay (MSIA) able to simultaneously assay for the new/novel biomarkers as well other MI markers is also presented. Means and methods for evaluating data generated using multiple biomarkers in order to validate findings and further the use of the multiplexed MI assay in clinical, diagnostic and therapeutic uses is also included. | 08-20-2009 |
