  • Patent number: 8030011
    Abstract: 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.

  • Publication number: 20100267069
    Abstract: 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.

  • Publication number: 20100267581
    Abstract: A microfluidic system and device capable of high throughput which includes a multi-channel micro-column having a high surface area material having at least one affinity reagent bound thereto contained within a housing. The structure of the housing and/or the multi-channel micro-column is of a sufficient size and configuration to enable capture and purification of an analyte contained within a sample and one or more of binding of a reporter molecule to the analyte and a substrate chemical reaction with the analyte to all take place within the housing and/or the multi-channel micro-column.

  • Publication number: 20080064044
    Abstract: Presented herein are affinity-based mass spectrometric methods and assays for analysis of insulin like growth factors 1 and 2 (IGF-1 and IGF-2) present in complex biological mixtures and fluids. IGF-1 and IGF-2 were assayed from human plasma via BIA/MS, utilizing antibodies as ligands for affinity retrieval. Detection of both targeted and non-targeted IGFs in the mass spectra indicated possible protein complex retrieval by the individual antibodies. Plasma samples were investigated under variable denaturing conditions to confirm the detection of both free and bound IGFs. In a MSIA approach to IGF detection, pipettor tips containing porous solid supports covalently derivatized with anti-IGF antibodies were used to extract specific IGFs from plasma in preparation for mass spectrometry. Single or multiplex IGF-1 and IGF-2 assays were performed, resulting in detection of wild-type IGF-1 and 2, and a truncated IGF-2 variant, missing its N-terminal Alanine (also detected in the BIA/MS experiments).

  • Publication number: 20070259447
    Abstract: Presented herein are methods, devices and kits for the mass spectrometric immunoassay (MSIA) of proteins and their variants that are present in complex biological fluids or extracts. 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 working curves constructed from samples containing known concentrations of the protein or variants.
