TUNEL Labeling Kits

    Apoptotic cells can be detected by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). R&D Systems offers kits designed for several different formats including Light Microscope-, Fluorescence/Flow Cytometry-, and Microplate Reader-based assays. We also offer colorimetric kits optimized for specific tissue types including Cardiac, Skin, Neuronal, Tumor, and Vascular cells and tissues.
