Small Bead Calibration Kits

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 – 100nm) however, these particles are difficult to detect using traditional methods, and require extra processing to segregate or characterize from debris commonly found in biological samples. Flow cytometry has emerged as a popular method of analysis and sorting for small particle characterization.

Size Calibration Standards

Our Size Calibration Standards Kit for flow cytometry is comprised of five populations of undyed microspheres in the range of ~4-11µm. Forward scatter channel (FSC) values may be plotted against reported bead diameter to generate a curve that may be used for estimation of the sizes of cells run at the same instrument settings. The Size Calibration Standards Kits are available in two sizes: B (100 tests) and C (280 tests).
