Abstract:
The invention provides methods, compositions, kits, and systems for the sensitive detection of cardiac troponin, Such methods, compositions, kits, and systems are useful in diagnosis, prognosis, and determination of methods of treatment in conditions that involve release of cardiac troponin.
Abstract:
The invention provides methods for diagnosing, predicting or prognosing acute myocardial infarction in an individual based on the sensitive detection of cardiac troponin.
Abstract:
Un método para determinar la presencia o ausencia de una única molécula de troponina, o un fragmento o complejo de la misma, en una muestra, que comprende: i) marcar dicha molécula, fragmento o complejo con una etiqueta que comprende una unidad estructural fluorescente; y ii) detectar la presencia o ausencia de dicha etiqueta haciendo pasar dicha etiqueta a través de una única molécula de detección, en donde la detección de la presencia de dicha etiqueta indica la presencia de dicha única molécula, fragmento o complejo de troponina en dicha muestra; y en donde dicha detección es capaz de detectar dicha única molécula de troponina en un límite de detección de menos 3 pg/mL con un coeficiente de variación (CV) de 10% o menos.
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, TNFa, IL- 17a) biomarkers provided a sensitivity of 94% for association with CHF.
Abstract:
Disclosed are methods, kits, and compositions for fluorescent detection of single biomolecules, e.g. proteins, using highly sensitive fluorescent dyes and a flow cell with one interrogation space for irradiation by focused laser beam. The methods, kits, and compositions are useful in determining concentrations of molecules in samples to levels of 1 femtomolar, 1 attomolar, or lower. The methods, kits, and compositions also allow the determination of concentration over a wide range, e.g., 7-log range, without need for sample dilution.

Abstract:
Un método para determinar un diagnóstico o pronóstico en un individuo que comprende: (i) medir la concentración de troponina cardiaca I (cTnI) a partir de una muestra de suero del individuo, en el que dicha concentración se determina mediante un ensayo de cTnI con un límite de detección para dicha cTnI en dicha muestra de menos de 5 pg/ml; (ii) comparar la concentración medida a una concentración umbral de 7 pg/ml; y (iii) determinar un diagnóstico o pronóstico de infarto de miocardio en el individuo, si la concentración de la muestra es mayor que la concentración umbral; en el que el individuo es un ser humano.

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.
