Daily Monitoring to Assess Instrument Performance

For a daily quality check, Quantum QC can be used to measure fluorescence at optimal PMT settings to ensure that the flow cytometer is performing its best. These PMT settings should be held consistent to gauge instrument performance day-to-day, and...

Daily Cytometer Setup using Quantum QC.

Setting PMTs to Ensure Consistent Fluorescence MeasurementsQuantum QC can be used to set up PMTs for measuring consistent fluorescence intensity day to day. One, or several, of the fluorescent peaks can be monitored daily and PMT levels adusted to...

I’m looking to do fluorescence quantitation using your Quantum MESF kits. One concern I had however was that my unlabeled cells have a lower fluorescence intensity than the blank bead. Why is that, and what do I do in this instance?

Our Quantum MESF and Quantum Simply Cellular beads are composed of polystyrene that have some level of autofluorescence varying based on the laser/channel in use. If you have control cells with lower MFI (mean fluorescence intensity) values than our...

My antibody isn’t binding to the Quantum Simply Cellular kit I just received. Can you help?

A first step is to confirm the host species of the primary antibody, as the most common reason for a complete lack of binding is antibody mismatch. We sometimes see clients mistakenly use the target species (of cells) when selecting the QSC kit,...
