PERFECT-COUNT Microspheres™
For In Vitro Diagnostic use

PERFECT-COUNT Microspheres™ is designed for determining absolute counts of cells in peripheral blood, bone marrow, leukapheresis and culture medium samples using flow cytometry.

PERFECT-COUNT Microspheres™ is cost effective and has a unique quality control.

PERFECT-COUNT Microspheres™ contains two different beads types (beads type A and beads type B) with different light scatter, fluorescence and floatation characteristics. Both types of microspheres remain stable for a long time, are easily detectable and differentiated by the flow cytometer because of their different fluorescence intensities. Bead A having low FSC, lower SSC, dimmer FL1, FL2 and FL3 expression and is FL4 negative, compared to Bead B which has low FSC, slightly higher SSC, brighter
FL1, FL2 and FL3 expression and is FL4 positive.
