Cell Meter™ Fixed Cell and Tissue TUNEL Apoptosis Assay Kit
Green Fluorescence
Cell Meter™ Fixed Cell and Tissue TUNEL Apoptosis Assay Kit provides a robust tool for conveniently detecting DNA fragmentation caused by apoptosis. The assay is a non-radioactive, simple, accurate and rapid method for monitoring apoptosis in. fixed cells and tissues via imaging DNA fragmentation. The TUNEL assay uses terminal deoxynucleotidyl transferase (TdT) to catalyze the incorporation of fluorescein-12-dUTP at the 3’-hydroxyl ends of the fragmented DNA. The fluorescein-labeled DNA is analyzed by fluorescence microscopy or flow cytometry (excitation at 488 nm with 530/30 nm emission filter). The kit can be used to detect apoptosis in fixed cells and formalin-fixed, paraffin-embedded tissue sections.
HeLa cells were fixed and treated with or without DNAse for 60 mins at 37 °C. The cells were then stained with Cell Meter™ TUNEL apoptosis assay kit. DNA strand breaks showed intense fluorescent staining in DNAse treated cells. The signal was acquired with fluorescence microscope using a FITC filter set.
