产品介绍： Interest in exosome and microvesicle analysis has grown rapidly in recent years as another way to explore disease states, cancer progression, and for drug discovery and delivery. Due to their small size (30 – 100 nm) however, these particles are difficult to detect using traditional methods, and require extra processing to segregate/characterize from debris commonly found in biological samples. Flow cytometry has emerged as a popular method of analysis and sorting for small particle characterization. The NanoBead Calibration kit comprises highly defined microspheres with an internalized fluorescent dye to allow users to determine the capabilities of their cytometer and appropriate instruments settings, as size references for small particle characterization, and assessing small particle handling processe
