Red Polystyrene Fluorescent Particles

Red Polystyrene Fluorescent Particles are high-quality monodisperse polymer microspheres embedded with bright, stable red fluorophores, ideal for flow cytometry calibration, fluorescence microscopy, immunoassays, and particle tracking applications. These red fluorescent polystyrene beads offer consistent size, uniform brightness, and excellent photostability, ensuring precise performance in instrument standardization, fluorescence intensity calibration, and biological labeling.Available in sizes ranging from 20 nm nanospheres to 10 µm microspheres, they are offered as plain, carboxylated, or amine-functionalized fluorescent latex particles, allowing easy conjugation with antibodies, proteins, or nucleic acids. Designed for quantitative fluorescence assays, red-channel flow cytometry reference standards, and fluorescent tracer studies, these red fluorescent microspheres provide reproducible optical signals compatible with PE/Texas Red filter sets, 561 nm lasers, and advanced fluorescence imaging systems.Each batch of red polystyrene latex beads undergoes strict quality control to ensure size uniformity, dye stability, and signal consistency, making them essential tools for diagnostics, cell analysis, biosensing, nanoparticle research, and biomedical imaging.
