Abvigen is dedicated to providing researchers with fluorescent particles of the highest quality and performance. To ensure minimal dye leaching and photobleaching, our particles are prepared either staining the particle core with a fluorescent dye or polymerizing a fluorophore in the presence of the particle core. Abvigen's fluorescent polymer microspheres are available in a wide range of particle sizes, colors, densities, and excitation/emission wavelengths.  They can be stored at room temperature or dispersed in aqueous media without compromising their fluorescent properties.

Key Advantages of Abvigen Fluorescent Particles:

• High Fluorescence Intensity and Particle Size Uniformity: Ensures consistent and reliable results.

• Broad Size Range: Particles range from a few nanometers to several hundred micrometers. 

• Versatile Matrix Options: Abvigen offers a variety of particle types, including: Polystyrene, Silica, PMMA, PVC, PLGA, PVA, Magnetic Particles, and Time-Resolved Fluorescent Particles.

• Surface Availability for Conjugation: Fluorophores are embedded within the bead matrix, leaving the particle surface fully available for adsorbing molecules of interest, such as COOH, NH2, Biotin, and Streptavidin. 

• Wide Range of Excitation and Emission Wavelengths: Accommodates diverse flow cytometry filter sets, including Red, Orange, Green, Blue, and many others.
