CountBright™ Plus Absolute Counting Beads
Catalog number: C36995
Description
CountBright Plus Absolute Counting Beads are a calibrated suspension of ~4 µm beads that encapsulate dyes that are excitable across a wide range of UV-IR wavelengths and brightly fluoresce in the emission range of 385-860 nm. In instances where a flow cytometer is not designed to provide absolute cell count, the use of absolute counting beads can help to determine the count. Absolute cell count is defined as the concentration of cells in the original sample.• Beads are on-scale with most cell types, including human whole lysed blood, for ease of use
• >95% singlets for improved accuracy
• Excited by UV-IR lasers for an expanded emission range (385–860 nm)
For Research Use Only. Not for use in diagnostic procedures.
