Invitrogen™ CountBright™ Plus Ready Tubes

Description

• CountBright Plus Ready Tubes offer the same advantages as CountBright Plus Absolute Counting Beads, but in ready-to-use tubes
• This not only improves the accuracy and repeatability of cell counting, but also allows for convenient room temperature storage for up to 12 months
• With a pre-calibrated quantity of CountBright Plus beads in each tube, any errors associated with handling and pipetting are eliminated
• While ideal for use with Lyse/No-Wash and No-Lyse/No-Wash workflows, these tubes are versatile enough to be used in any flow cytometric assay where precise cell counts are necessary
• Plus, with benchtop storage, CountBright Plus Ready Tubes are always at the ready when you are
• CountBright Plus Absolute Counting Beads 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)
