Marker Screen, human, version 02 has been designed for screening and analysis of 378 human markers by flow cytometry. Flow cytometry is an efficient tool for analyzing differential protein expression in heterogeneous cell populations, in sample cohorts, or in response to different culture and experimental conditions. The kit combines the benefits of flow cytometry and high quality pre-titrated antibodies to screen for markers of interest in a standardized and high throughput manner. Identified markers or combinations of markers can serve to better characterize cell compositions or cells of interests, e.g., for quality
