Fluorescent Microspheres

FluoSpheres® and TransFluoSpheres® polystyrene fluorescent microspheres can be used for a wide range of applications including blood flow determination, tracing, in vivo imaging and calibration of imaging and flow cytometry instruments. Because our dyes are incorporated throughout the bead and not just on the surface, they are relatively immune to photobleaching and other environmental factors.

Blood Flow Determination & Tracing

Our microspheres for blood flow determination are available in eleven distinguishable fluorescent colors and are compatible with blood flow analyzers.

Flow Cytometry Calibration

These fluorescent microspheres provide flow cytometry users the means to calibrate laser alignment, compensation, flow rate, dynamic range and other daily adjustments. Bead dyes are spectrally matched to common lasers and are highly stable.

Imaging Calibration

We provide six different types of reference standards designed to facilitate adjustment and calibration of both conventional fluorescence microscopes and confocal laser-scanning microscopes.

 

Products

In vivo Imaging

Microspheres specifically designed for vascular imaging, graft migration, neuronal tracing, pulmonary ventilation, phagocytosis and time-resolved detection of rare targets in tissues.
