DEVICE TO BE USED FOR CAPTURING EXTRACELLULAR VESICLES, AND PRESERVATION METHOD AND TRANSPORT METHOD FOR EXTRACELLULAR VESICLES

摘要

The present invention provides a novel miRNA extraction method and a method for analyzing miRNA extracted by using said miRNA extraction method. According to the present invention, provided is, for example, a method for extracting miRNA from extracellular vesicles in a sample solution, by using a device capable of capturing extracellular vesicles, the miRNA extraction method comprising: an extracellular vesicle capturing step for capturing extracellular vesicles in a sample solution onto a device by bringing the sample solution and the device in contact with each other; and a miRNA extraction step for homogenizing the extracellular vesicles by bringing the device having captured the extracellular vesicles in contact with a homogenization liquid for extracellular vesicles to extract miRNA from the extracellular vesicle into the homogenization liquid.
