AQUIOS Lysing Reagent Kit consists of two reagents (Reagent A and Reagent B) used by AQUIOS flow cytometers to prepare whole blood samples for analysis of white blood cells. Reagent A lyses red blood cells in whole blood samples sufficiently to perform monoclonal antibody panel analysis without interference from red blood cells. Reagent B slows the lysing reaction sufficiently to allow analysis without damage to white blood cells. The lysing reagents are placed onboard the system and are barcoded, which allows the system to detect their presence and position. High volume users can load multiple containers and the system will automatically move from one container to the next as needed.
