Intracellular Flow Cytometry

Unlike traditional flow cytometry for cell surface markers staining, intracellular flow cytometry brings us a powerful tool to stain intracellular target proteins, such as phosphorylated signal transducers, transcription factors and cytokines. Through fixation and permeabilization, antibodies are able to penetrate the cell and nuclear membranes to stain target proteins within the cell. Proteintech offers a range of antibodies for intracellular flow cytometry single cell analysis with optimized fixation and permeabilization reagents for reproducible results.
