Web3 Keys To Creating High Quality Compensation Controls. 1. Account for brightness. You may be wondering whether the compensation matrix may be irrelevant and inaccurate if compensation controls signal intensities are not exactly matched to the experiment’s samples. The answer is a firm no: they don’t need to be matched. WebDoublet exclusion ensures that only single cells are included in the flow cytometry analysis. This is critical for reducing false positives in flow cytometry. Doublets can be identified on FSC-A vs FSC-H (area vs height) plots. They have a larger area compared to singlets, while maintaining a similar height. litho-printinghttp://web.mit.edu/flowcytometry/www/FSC-A%20Scaling.pptx litho printing definition
