As a researcher, you want to achieve the best cell sorting possible. So, how can you achieve that? There are clear strategies you can use to achieve great cell sorting results, including finding your ideal sample concentration, using magnetic sorting to enrich your population, suspending cells in the right buffer to avoid cell clumps, changing your instrument settings when sorting small cells, and optimizing your sample preparation and instrument when sorting large cells.

5 Essential Beads For Flow Cytometry Experiments

Pin It

Flow cytometry is designed to measure physical and biochemical characteristics of cells and cell-like particles using fluorescence. Fundamentally, any single-particle suspension (within a defined size range) can pass through the flow cytometer. Beads, for better or worse, are a sine qua non for the flow cytometrist. From quality control,to standardization, to compensation, there is a bead for every job. They are important — critical, even — for flow cytometry.

Use This Preparation Guide For Accurate Flow Cytometry Results

Pin It

There is a lot of preparatory work that must be done before the first flow cytometry experiment can be attempted. Each step builds upon the previous one and extends where the assay is going. Be prepared for some trial and error in this process, and don’t expect perfect results the first time around. An educated user is a good user, and makes the SRL staff’s job that much easier. The partnership between investigator and SRL staff is a rewarding one, when both parties work together to achieve the ultimate goal of generating excellent data and sort results that help answer the biological question being tested.

5 Essential Calculations For Accurate Flow Cytometry Results

Pin It

Flow cytometry is a numbers game. There are percentages of a population, fluorescence intensity measurements, sample averages, data normalization, and more. Many of these common calculations are useful, but surrounded by misconceptions. This primer will help you decide which calculation to use, when to use it, and how to interpret the results.

How To Use A Threshold To Reduce Background Noise In Flow Cytometry

Pin It

Getting a clear signal with reduced noise is an essential component to good data. Adding a threshold when acquiring flow cytometry data is one way to do that. It reduces the number of events by setting a bar that a signal pulse must clear before it is counted as an event. Depending on the importance of the data, the downstream applications for the data (or sorted cells) will dictate how critical the threshold is. In combination with proper sample preparation, appropriate thresholding will reduce debris and ensure best outcome.
