Analyzing cell populations in whole blood is a fundamental yet challenging task. Even after standard preparation steps, samples often contain mixed populations of leukocytes, platelets, and red blood cells (RBCs). Cytely enables researchers to rapidly identify and quantify these populations at the single-cell level. Through scatter plots and intuitive gating, different blood cell types can be distinguished and characterized in an unbiased, interactive workflow. Key features demonstrated in this note: Visualizing heterogeneity across a mixed cell population Identifying populations (neutrophils, platelets, RBCs) using scatter plots Gating to isolate neutrophil subsets
