FIELD: medicine, pharmaceutics.
SUBSTANCE: group of inventions relates to a method of measuring troponin I in a sample. For this purpose the sample is provided. After that, the sample is brought in contact with a monoclonal antibody to troponin I, bound with a magnetic label. Then, the sample is brought in contact with the polyclonal antibody or with two different antibodies to troponin I, bound with a sensor surface. The said antibodies are aimed at an amino acid sequence 30-110 of troponin I. After that, the detection of the magnetic label on the sensor surface is carried out. The group of inventions also relates to a device and a cartridge for measuring troponin I in the sample.
EFFECT: inventions make it possible to carry out diagnostics of myocardium infarction within 5 minutes and with the application of the small-volume sample.
