Gating can be one of the more time-consuming parts of cytometry analysis. When gate positions need to be changed for every sample in an experiment, it can take orders of magnitude longer. Two automatic tools built into CellEngine, CellCarta’s cytometry analysis platform, can be leveraged to increase speed and efficiency:
In order to streamline the gating process most efficiently, there are several important points to remember when usingthese tools.
1 – Experiment design underlies every successful analysis
Experimental design is a fundamental factor for successful cytometry analysis. Autogating in CellEngine streamlines the analysis process, but the best results come from well-designed trials and high-quality data. Taking time to design clear objectives, include appropriate controls, and optimize experimental conditions ensures that the results from autogating are meaningful and useful. For example, including an unstimulated control in an intracellular cytokine or phospho-flow panel provides an ideal control for using percentile gating. Picking dyes that provide good separation of populations improves automatic gate tailoring’s performance. By creating a well-designed foundation, researchers can extract meaningful insights from complex datasets.
2 – Quality control is indispensable
One of the most important aspects of high-quality analysis is high-quality data. To generate high-quality data, build quality control processes into your workflows to ensure reliability and accuracy, and identify issues promptly. For example, verify staining via positive controls, use beads to calibrate and verify cytometer performance, and reduce technical variability as much as possible. This maximizes the potential from each dataset, whether you use automatic tools in analysis or not.
3 – Train algorithms with representative data
Automatic gate tailoring uses one or more files as a reference for setting gate positions. Training data must be representative of the overall dataset, and carefully gated for best results. An experiment with different cell types, disease states, or experimental conditions should include examples of all of those in the training data. This enhances the algorithm’s ability to properly adjust gates. Consistent choices when gating the training data will also reduce variability.
Combining meticulous experiment design, trustworthy data, and carefully curated training data with automated tools increases efficiency and accuracy. By incorporating these best practices, researchers can harness the full power of autogating tools to optimize their workflows.
