Flow analysis method in particle research

Circulated microparticles ( cMPs ) are small vesicles with a diameter of less than 1 μm that are detached from the cell membrane after cell activation, injury or apoptosis. In diabetes, cardiovascular disease, AIDS, chronic inflammatory diseases, circulating microparticles are found to be elevated, and some of its biological activities, such as the transmission of intercellular biological activity signals, immune regulation of angiogenic tissue repair, etc., and disease occurrence Development is closely related. The understanding of it is still being explored continuously, and its research is also increasing.

Circulating microparticles are different from apoptotic bodies and exosomes. Apoptotic bodies are formed by budding when cells are apoptotic.   1 μm ; exosomes are vesicle particles released by cell activation, released in an exocrine form, with a diameter ranging from 10.0 nm to 100 nm.   . The diameter of the circulating particles is approximately   0.1 μm - 1 μm , they have similar basic characteristics to the mother cells.

At present, the detection of microparticles is mainly detected by ELISA and flow cytometry. The ELISA method is susceptible to interference by other soluble antigens, and the storage time and mode of whole blood or plasma, the processing method of the sample, and different detection methods all affect the results of particle detection. The flow cytometry method provides a more efficient and rapid analysis of particle analysis capabilities. A variety of flow cell markers are available for the detection of microparticles, which are primarily used to detect the activation state of the microparticles and their cellular origin. However, particles detected by flow cytometry are difficult to detect due to wavelength limitation, and particles having a diameter of less than 0.3 μm to 0.5 μm .
