    Cyto-Cal™ Count Control


    1. 详细信息

    Ensure an accurate count verified by analytical procedures with Thermo Scientific™ Cyto-Cal Count Control, which consists of fluorescent beads for absolute counting on flow cytometers. With its hydrophilic bead surface, the count control eliminates particle doublets and guarantees accurate count.


    • Uniform 7μm microspheres contain two encapsulated dyes
    • Single vial contains fluorescent beads that are precisely stained with fluorescent dyes that have optimized intensity and broad emission in multiple channels (FITC, PE, PE-Cy5)
    • Cyto-Cal 488 Alignment beads are excited by the 488nm spectral line of the argon laser and have broad emission, allowing them to be used to align the FL1 (FITC), FL2 (PE) and FL3 (PE-Cy5) channels simultaneously
    • Cyto-Cal 633 Alignment beads are optimally excited with the 633nm He-Ne laser (635nm diode laser) and have a maximum emission at 700 nm. They are designed to align the FL4 (APC) channel

    Recommended for:

    Liquid particle counting and sizing calibration. Product can assist in USP <788> and <789> interim verification.
