Webthe proper threshold value for any given experiment. This is illustrated in Figure 4. Using the default threshold of 80,000, the BD Accuri C6 flow cytometer should be able to visualize a 1-µm bead using an FSC-H vs SSC-H plot. However, since the bead falls very close to the threshold value, this threshold might not be appropriate. WebThis process consists of 5 steps: 1. Set the Null Hypothesis. The null hypothesis (H 0) is a statement of what we think the state of the system is. In this case, the state of the system after treatment would be that there was no change in the system — i.e. the means between control and experimental are equal.

WebData analysis is the key to being able to unlock the power of flow cytometry. It allows you to see populations with the combinations of parameters that you define using Boolean logic. Plots visually display the data. Histograms (single parameter plots) and 2-parameter dot plots are the most commonly used types of plots. Webthreshold level is too low, you will have an increased abort rate due to the noise. Ultimately, you should try to keep the abort rate below 5-10 % either by adjusting the threshold, the sample concentration, or the flow rate. Keeping the sample concentration and flow rate low is also important to prevent experimental artifacts due to coincidence
