Immunophenotyping in cancer research using flow cytometry

Flow cytometry allows identification of cellular markers through surface or intracellular staining techniques. These markers can be used to identify different cell types, which is useful in developing cell-specific therapies. 

Furthermore, flow cytometry’s ability to characterize, count, and sort fluorescently labeled cells based on their phenotype affords it yet another advantage in immuno-oncological applications. Quantification and characterization of specific subsets of cell populations allows us to better ascertain the immunogenicity of a therapy, and thereby enhance our understanding of complex immune responses. 

Our new and advanced flow cytometry instruments, as well as an expanded range of antibodies and fluorochromes to accompany the technique, enable more accurate phenotyping of cells, which in turn enables enhanced identification of cellular distribution in the cancer environment.  
Key features and advantages of flow cytometry include:  

• The ability to analyze single-cell suspensions, for example immunophenotyping directly from whole-blood samples 
• Easy analysis of rare cell events with statistical significance because of the ability to acquire in excess of 4,000,000 events 
• The ability of flow cytometers to perform high-content and complex phenotyping makes this the gold-standard for immunophenotyping and immune response profiling 
• High suitability for multiplexed detection of markers of interest (intracellular, surface markers, phosphoproteins) and compatibility with high throughput 
• Appropriateness for multiplexed detection of secreted biomarker molecules, e.g., cytokines, in a multitude of biological samples, such as supernatants, blood derivatives, and tissue homogenates
