Display and correction of flow cytometry time-dependent fluorescence changes

Area of Science:

• Biomedical Engineering
• Cell Biology
• Analytical Chemistry

Background:

• Flow cytometry is a powerful technique for analyzing cellular attributes based on fluorescent marker labeling.
• Variations in staining intensity and sample stream flow can introduce time-dependent errors during data acquisition.
• These variations can compromise the accuracy and resolution of flow cytometry measurements.

Purpose of the Study:

• To introduce a novel method for visualizing and correcting time-dependent variations in flow cytometry data.
• To improve the reliability and accuracy of cellular attribute measurements obtained by flow cytometry.
• To address the impact of staining and flow rate fluctuations on data quality.

Main Methods:

• Analysis of list mode data in chronological order.
• Development of a display method to visualize time-dependent changes.
• Implementation of a correction strategy for identified variations.
• Utilizing chronological data to identify and adjust for fluctuations.

Main Results:

• Successful display of time-dependent variations in flow cytometry data.
• Demonstration of effective correction for staining and flow rate induced changes.
• Improved resolution and accuracy of cellular attribute measurements.
• Validation of the chronological data analysis approach.

Conclusions:

• The described method effectively addresses time-dependent variations in flow cytometry.
• Accurate cellular attribute measurement is achievable by correcting for data acquisition inconsistencies.
