What are you using to measure results in your flow cytometric study?

See how the Quantum MESF system has been used to standardize studies and quantify results in a range of applications:Singh H, Figliola MJ, Dawson MJ, Olivares S, Zhang L, et al. (2013) Manufacture of Clinical-Grade CD19-Specific T Cells Stably...

I’m using your Quantum Simply Cellular (QSC) beads to quantitate cell surface receptors, but I’m fixing my cells as part of my standard prep. Do I also need to fix the beads as well?

Sample handling/prep can certainly play a large role in quantitative flow cytometry, although we recommend against using fixation steps for our beads, as many of the fixatives are known solvents of our polystyrene particles (e.g. formaldehyde or...

I ran some beads and noticed there are two or three populations. I thought the beads were only a single size? What’s going on?

What this user is noticing is likely aggregation of the beads. FSC/SSC (forward scatter / side scatter) dot plots provide general information in terms of size (FSC) and granularity (SSC). When two particles are stuck together, the instrument will...
