Concanavalin A (ConA) is a lectin (carbohydrate-binding protein) originally extracted from the jack-bean, Canavalia ensiformis. It is a member of the legume lectin family. It binds specifically to certain structures found in various sugars, glycoproteins, and glycolipids, mainly internal and nonreducing terminal α-D-mannosyl and α-D-glucosyl groups. ConA is a plant mitogen, and is known for its ability to stimulate mouse T-cell subsets giving rise to four functionally distinct T cell populations, including precursors to suppressor T-cell; one subset of human suppressor T-cells as well is sensitive to ConA. ConA was the first lectin to be available on a commercial basis, and is widely used in biology and biochemistry to characterize glycoproteins and other sugar-containing entities on the surface of various cells. It is also used to purify glycosylated macromolecules in lectin affinity chromatography, as well as to study immune regulation by various immune cells.
An integrated microfluidic portable sensor air bacteria electrostatic collection and real-time monitoring system and method
The application discloses an air bacterial electrostatic collection and real-time monitoring system and method integrated with a microfluidic portable sensor, and belongs to the technical field of environmental monitoring, and comprises an aerosol sampling module, a microfluidic processing module, an electrochemical sensing module and a portable constant potential instrument module. Bacteria aerosols in the ambient air are charged by corona discharge to realize efficient enrichment and collection; the enriched liquid sample is sent into the microfluidic processing module and flows through a sensing electrode modified with CuFeCoPBA@MoS2 nano composite material, polydopamine and concanavalin A. Target bacteria are combined with the concanavalin A on the surface of the electrode in a broad-spectrum specific manner, the interface electron transfer is hindered, the portable constant potential instrument collects the attenuation change of differential pulse voltammetry electrochemical signals, and rapid quantitative detection of the concentration of air bacteria is completed. The application integrates efficient air aerosol collection and portable biosensing, and can realize one-step on-site capture and detection of air pathogens.
