Particles for Absolute Cell Counting using a Single-Platform Flow Cytometric Method. Reference particles with known number of particles per mL for counting the absolute cell number by flow cytometry

Spherotech offers a wide variety of particles for determining if a flow cytometer is properly aligned and has a clean flow cell with no fluidic blockage. Using SPHERO™ Alignment Particles, the coefficients of variation (CVs), peak channels, and histogram distributions can be measured to determine the alignment and functionality of the flow cytometer.

The SPHERO Calibration Particles are designed for routine calibration of flow cytometers. By using these particles, the sensitivity and linearity of the system can be determined. The sensitivity of the instrument will help detect any dye or light contamination. The linearity of the instrument will determine if the logarithmic amps and PMTs are functioning properly.
