One-Step Universal TUNELApoptosis Kit

This one-step universal TUNEL apoptosis kit provides a rapid and sensitive method for detecting apoptotic cells in a variety of sample types. The kit utilizes terminal deoxynucleotidyl transferase to catalyze the incorporation of fluorescently labeled dUTP onto the exposed 3'-OH ends of fragmented genomic DNA, a hallmark of apoptosis. This method enables direct detection of apoptotic cells by fluorescence microscopy or flow cytometry, making it a versatile tool for apoptosis research. Unlike necrotic cells or cells with DNA strand breaks caused by irradiation or drug treatment, apoptotic cells produce characteristic DNA fragments of 180 to 200 base pairs and can be specifically labeled with minimal background staining. In histology laboratories where tissue sections are prepared using Paraffin Microtome, this kit is frequently employed to detect apoptotic cells in tissue sections, enabling precise localization of apoptosis within complex tissue architectures and supporting research o…
