Abstract: This disclosure provides, in one aspect, a method for analyzing a sample from a subject for a biomarker that is indicative of the subject's immune response to ?-glucan. Generally, the method includes obtaining a biological sample from a subject, analyzing the sample for a biomarker anti-?-glucan antibody compared to a reference standard, computing a Relative Antibody Unit (RAU) value for anti-?-glucan antibody in the sample, and identifying the subject as biomarker positive if the RAU value is greater than a predetermined RAU value for the biomarker anti-?-glucan antibody.

Abstract: Methods for proteomic screening on random protein-bead arrays by mass spec is described. Photocleavable mass tags are utilized to code a protein library (bait molecules) displayed on beads randomly arrayed in an array substrate. A library of probes (prey) can be mixed with the protein-bead array to query the array. Because mass spec can detect multiple mass tags, it is possible to rapidly identify all of the interactions resulting from this mixing.

Abstract: We identified >40 proteins that elicited at least a 2-fold increase in antibody response post-pancreatic-cancer vaccination, from each of three patients' sera. The antibody responses detected against these proteins in patients with >3 years disease-free survival indicates the anti-tumor potential of targeting these proteins. We found that tissue expression of proteins PSMC5, TFRC and PPP1R12A increases during tumor development from normal to pre-malignant to pancreatic tumor. In addition, these proteins were shown to be pancreatic cancer-associated antigens that are recognized by post-vaccination antibodies in the sera of patients that received the vaccine and have demonstrated a favorable disease free survival.

Abstract: Specific peptides, and derived ionization characteristics of the peptides, from the Insulin Receptor protein (IR), and its isoforms IR-A and IR-B, that are particularly advantageous for quantifying the IR protein, IR-A isoform and/or IR-B isoform, directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM) mass spectrometry. Such biological samples are chemically preserved and fixed and are selected from tissues and cells treated with formaldehyde containing agents/fixatives including formalin-fixed tissue/cells, formalin-fixed/paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, and tissue culture cells that have been formalin fixed and or paraffin embedded.

Abstract: This disclosure describes assay methods and kits for detecting a target. The methods and kits can be used to detect a target that is present in a sample at low concentration because the methods and kits amplify the signal indicating the presence of target in the sample. Generally, the methods and kits involve nanoparticle aggregation as a detectable signal that is enhanced by a trigger released from a vesicular compartment when the target is bound to a capture agent.
Abstract: Provided is a method of bioassay for the quantification of peptide fragments elevated in lung diseases such as COPD, SCC, or IPF. The peptide fragments comprise a neo-epitope formed at a cleavage site by cleavage in vivo of elastin by a proteinase. In the method a sample is contacted with an antibody having specific binding affinity for the neo-epitope amino acid sequence and determining the level of binding is determined where the antibody binds one of the following terminal sequences: . . . FGPGVV, . . . VPGLGV or IKAPKL . . . . Also provided are antibodies and immunoassay kits for use in such methods.

Abstract: Methods and compositions are provided for diagnosing ectopic pregnancy in a mammalian subject by detecting changes in expression of the selected genes, gene fragments or transcripts or expression products, or changes in the expression levels of one or more of proteins or peptide fragments, identified in Table 2 and FIGS. 8 and 9 herein. A selected gene, gene transcript or protein/peptide expression product, or profiles or signatures formed by combinations of same, detected in a biological fluid, preferably sera, of a subject, enables comparison of the corresponding genes, proteins or profiles from that of a reference or control having a normal intrauterine pregnancy. Detection of characteristic changes in the gene profile or protein expression signature of the subject is correlated with a diagnosis of ectopic pregnancy.
