PolyAn's Spectrum Calibration Nanobeads are monodisperse PMMA sub-micron particles that are available in different sizes between 100 nm and 600 nm. The beads contain a mixture of highly photostable fluorescent dyes that can be excited at any wavelength from 365–650 nm and emit at 400–750 nm, which enables their detection in all common fluorescence detection channels (DAPI, FITC, PE/TAMRA/Cy3®, APC/Cy5®, Cy7®) with only minimal photobleaching.

PolyAn’s Spectrum Calibration Nanobeads are particularly useful to calibrate imaging setups for multi-color applications and to check their capability to resolve and co-localize very small fluorescent objects of different color in the same optical plane. As the Spectrum Calibration Nanobeads resemble the size of extracellular vesicles (EVs), they can also be used to adjust flow cytometers for EV detection.

About PolyAn

PolyAn is a nanotechnology company specialized in Molecular Surface Engineering. Since 1996 PolyAn develops and manufactures consumables for multiplex diagnostic and LifeScience research. This includes a wide range of fluorescence encoded PMMA micro- and nanoparticles (beads) for flow cytometry, imaging, and bead-based assays. PolyAn also offers functionalized plates for immunoassays (e.g. ELISA), calibration tools for fluorescence imaging systems, as well as the broadest portfolio of microarray consumables (slides, coverslips, plates) on the market.
