C-Pak Single peak alignment particles
The Carboxyl Blue PAK (C- PAK) particles are fluorescent in PE-Cy5, APC, and APC-Cy7 channel
with minimal fluorescent in FITC and PE channels with
488 or 635 nm excitation. These beads are 7.6uM in diameter and are ideal for performing time delay calibration on the BD 4-color cytometers.
