Double-clicking on the new population will generate the corresponding graph lower panel, right. Applying the Boolean AND gate will select this sub-population shaded in red in the picture below.įlowJo will present a new population and statistic of this sub-population lower panel.

Assume you are interested in the sub-population of Lymphocytes-1 and -2 that expresses only high levels of antigen A and low levels of antigen B. Gates must have some area of overlap to create an AND Boolean gate. Hypothetical Experiment for Boolean gating.ĪND Boolean gating creates a population of an area of overlap between 2 or more populations. Gooseneck flag mountĭepending on your interests, you may wish to include or exclude certain sub-populations from your analyses. It may be necessary to first drag the Boolean band from the customize ribbon into the Workspace. To create Boolean gates, select the Boolean band from the Workspace ribbon. You can read more about gating at the links below.Need to find that complicated sub-population? You may wish to do more complicated gating to identify certain sub-populations. Gating Menu FlowJo X has a variety of gating options available in the graph window interface. Gating Defined Gating refers to the process of selecting a subset of the collected events for further analysis. There are also ranged gates and the bisector tool which are only available for use with univariate plots histogramsCDFshown below. Gating options are located above the graph and are shown in the screenshot below. In general, avoid using duplicate names of subpopulations within any given sample.įlowJo X has a variety of gating options available in the graph window interface. Siblings subsets from the same parent but displaying different parameters with the same names are not allowed to avoid confusion. The process of gating simply creates a new population. The child gate on the right only contains the population of cells contained within the parent gate. In the figure below a polygon tool was used to draw a star- shaped parent gate left. Flow Cytometer Basics and FLOWJO Analysis This population is often referred to as the child gate, and the population that created it is called the parent gate. Once a gate is created with a gating tooldouble clicking on the gate will open a new Graph Window displaying the selected population.

For more on group-owned gates, go here.Ī variety of gate properties can be set by changing the gate preferences. Note the change in statistics in the Graph Window as well as the workspace. To use it, first draw a gate with anything but the rectangle tool. All polygon not quadrant except the rectangle tool can be expanded or contracted using this feature.

For finer movements, select a gate and use the arrow keys on the keyboard to move the gate one pixel in the direction of the arrow key. If you want to move the entire gate, mouse within the selected gate the cursor will change to a four-sided arrowthen click-and-drag it to the new location. FlowJo will also adjust the statistics column in the workspace and any other statistics that are dependent on the adjusted gate. Note the updated statistic within the red boxes in both graphs. To move a vertex, select a gate, click on the vertex handle black square, highlighted by a red circle below and hold the mouse button down while dragging the vertex to a new location shown below. Need to tighten that gate to remove doublets or debris? Was that lymphocyte gate too generous? FlowJo allows you to adjust gates at any point during your analysis with immediate updates to statistics, tables and layouts.Īnalyzing flow cytometry data often requires adjustment to previously defined gates in order to accomodate or remove certain groups of events.
