Flow cytometry with the MACSQuant Family of flow cytometers is all about performance, automation, compactness, and convenience. The MACSQuant VYB not only combines these features, but also comes with a uniquely configured optical bench, featuring violet, yellow, and blue lasers. It is a perfect match for labs utilizing fluorescent protein reporters or for labs that want to simply use PE and FITC conjugates.

|1 At every uptake, an additional excess volume is aspirated by the instrument. The excess volumes are calibration- and process-dependent and do not exceed 10 μL for Fast, Standard, and Extended modes, and 20 μL for Screen mode.|
2 Referred value indicates the average of multiple experiments and can differ for individual sample materials.
3 The measurement speed is determined by measuring the time between the movement of the robotic arm into the first measured well, and its movement out of the last measured well. The measurements were carried out at high flow rate in fast mode.
4 For carry-over, full 96-well plates were loaded with 200 μL/well of PBMC suspension at a nominal concentration of 10,000 cells/μL in every other well ("SRC-wells”). Alternating wells are loaded with an equal volume of MACSQuant® Running Buffer ("CO-wells”). The uptake volume was set to 100 μL and measured at medium flow rate in standard mode. The carry-over is defined by sum (CO-singlet count)/sum(SRC-singlet count) ×100%.
