In fluorescence flow cytometry, spectral overlap among multiple fluorescent labels cannot be avoided, and thus detected intensities need to compensated. Although compensation in cytometry has been widely used for many years, it still lacks quantitative evaluations validate its effectiveness. Using a home-developed nine-color cytometer, this study first obtains calibration curves by assaying gradient concentrations of nine different fluorochromes individually, with the highest each fluorochrome being obtain spillover matrix. Mixed solutions are analyzed which obtained compensated matrix, translated specific based on curve compared nominal values. Three mixed Brilliant Violet 650 711, Alexa Fluor 488 PE, Pacific Orange, 488, PE tested, observed reduce excessive signals due overlap. Specifically, concentration deviations (before vs after compensation) comparison values 711 quantified as 40.6% 14.9% 6.7% 1.9%, respectively. The results presented here provide reference that can effectively address issue cytometry.
