By utilizing highly specific antibodies labeled with fluorescent conjugates, FACS analysis allows us to simultaneously collect data on, and sort a biological sample by a nearly limitless number of. Flow Cytometry Kits & Antibodies MilliporeSigma's Milli-Mark and FlowCellect brands include fluorescent conjugated antibodies and multiparameter kits for cellular analysis.
