Blood immune cell flow cytometry analysis is a standard practice in both research and clinical labs. The immune cell preparation from whole blood samples normally requires multiple manual cell washing steps with centrifugation.The process can be tedious, labor intensive, time consuming, and inconsistent. We developed a new sample preparation MARS system, using an acoustic active-microfluidic chip-wash to remove red blood cell debris, free dyes or other small particles. The MARS system automates the sample preparation for multicolor immuno-staining of white blood cells with high speed and cell recovery with minimal hands-on time.
