Abstract:
The invention encompasses analyzers and analyzer systems that include a single molecule analyzer, methods of using the analyzer and analyzer systems to analyze samples, either for single molecules or for molecular complexes. The single molecule uses electromagnetic radiation that is translated through the sample to detect the presence or absence of a single molecule. The single molecule analyzer provided herein is useful for diagnostics because the analyzer detects single molecules with zero carryover between samples.
Abstract:
A single molecule analyser comprises an electromagnetic radiation source for providing radiation to a substantially transparent sample container holding one or more samples, a system for directing radiation to an interrogation space in a sample such that the sample emits radiation from a single type of label attached to a single molecule, a translating system for translating the sample container to form a movable interrogation space in a sample, a microscope objective to define the interrogation space, a detector for detecting radiation from the label attached to the molecule, and analysis means to determine presence of the single molecule. The single molecule analyzer is useful for diagnostics as the analyzer detects single molecules with zero carryover between samples.
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 (cTnI) 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:
A method for detecting and monitoring a condition in a subject using a single molecule detector is disclosed comprising detecting a first marker in a first sample from the subject, wherein the first marker comprises a biomarker such as Cardiac Troponin-I (cTnI), and wherein the limit of detection of the first marker is less than 20 pg/ml, and further comprising the detection of a second marker as a further indication of the condition to be detected. The second marker can be a biomarker, physiological marker, a molecular marker or a genetic marker. Also claimed are similar methods involving the detection of Vascular Endothelial Growth Factor (VEGF), pro B-type Natriuretic Peptide (proBNP), TREM-1, Interleukin 1 Alpha (IL-1 a ), IL- 1 b , IL-4, IL-6, IL-8, IL-10, Interferon gamma (IFN- q ), Tumour Necrosis Factor alpha (TNF- a ), Glucagon-like peptide-1 (GLP-1), Leukotriene E4 (LTE4), Transforming Growth Factor Beta (TGF- b ), Akt1, A b -40, A b -42, and Fas ligand (FasL). The markers may be detected using fluorescent labels.
