Abstract:
A method for characterizing a carcinoma in a subject. The method comprises assaying a sample of a bodily fluid derived from the subject for extracellular PKA activity and comparing the activity to a reference value. In the assay, a reaction mixture is prepared comprising the previously unfrozen sample, a PKA peptide substrate, a phosphorylation agent, the prepared mixture is incubated, and phosphorylated substrate formed in the incubated mixture is detected. The reference value is the amount of phosphorylated substrate formed in a mixture under equivalent redox conditions for a sample of bodily fluid derived from a population of normal subjects of the same species.
Abstract:
The present disclosure relates to methods for determining the presence, activity, and/or concentrations of certain cancer biomarkers and their use in determining the presence of cancer.
Abstract:
The present invention discloses methods for the detection and monitoring of a condition in a subject using highly sensitive detection of molecules. The invention provides a method for detecting or monitoring a condition in a subject, comprising detecting a first marker in a first sample from the subject and detecting a second marker, wherein the first marker comprises a biomarker, e.g., Cardiac Troponin-I (cTnl) or Vascular Endothelial Growth Factor (VEGF), and wherein the limit of detection of the first marker is less than about 10 pg/ml. The second marker can be a biomarker, physiological marker, a molecular marker or a genetic marker.
Abstract:
The invention encompasses analyzers and analyzer systems that include a single particle analyzer, methods of using the analyzers and analyzers systems to analyze samples, either for single particles of for multiple particles (multiplexing), methods of doing business based on the use of the analyzers or analyzer systems of the system, and electronic media for storing parameters useful in the analyzers and analyzer systems of the invention.

Abstract:
The present invention relates to a method of detecting the presence of cancer by measuring the level of enzyme activity and autoantibodies in the blood of an individual. In particular the present invention relates to methods for measurement of activated cAMP-dependent protein kinase A (PKA) activity and antibodies to PKA, a kit for activated PKA activity measurement, and the use of the measured levels of these analytes for determining the presence of cancer.

Abstract:
Cardiovascular disease, e.g., congestive heart failure, is often first diagnosed after the onset of clinical symptoms, eliminating potential for early intervention. The invention provides a multi-marker immunoassay, including cardiac pathology and vascular inflammation biomarkers, yielding a more sensitive assay for early detection of CHF in plasma. A panel consisting of cardiac pathology (cTnl, BNP) and vascular inflammation (IL-6, TNFα, IL- 17a) biomarkers provided a sensitivity of 94% for association with CHF.
