TUNEL Assay Kit (Fluorescence, 594 nm) #48513

    Product Information

    Protocol

    Product Description

    TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling) is a method by which a fluorophore conjugated nucleotide is enzymatically linked to the 3′ end of fragmented DNA. Since DNA fragmentation is a hallmark of apoptosis, the TUNEL assay has become a well established method to monitor apoptosis in situ.

    The TUNEL Assay Kit (Fluorescence, 594 nm) provides you with the buffers, enzyme, and dUTP fluorophore conjugate necessary to complete the TUNEL reaction in fixed cells or tissue. This kit is intended for use with fluorescence microscopy and/or flow cytometry.

    Fluorescent Properties

    • Excitation maximum = 593 nm/Emission maximum = 614 nm

    Specificity / Sensitivity

    Tissue processing or cell degradation may result in labeling of nuclei in non-apoptotic cells.

    Background

    Apoptosis is a regulated cellular suicide mechanism characterized by nuclear condensation, cell shrinkage, membrane blebbing, and DNA fragmentation (1). During late stages of apoptosis, DNA is fragmented by an endonuclease that cleaves the chromatin into nucleosomal units which can be visualized on gels as DNA laddering (2). DNA fragmentation also serves as a basis for monitoring apoptosis in situ using the TUNEL assay (3). In this assay, terminal deoxynucleotidyl transferase enzymatically incorporates a fluorophore conjugated nucleotide to the 3' end of fragmented DNA. Apoptosis can be monitored by an increase in TUNEL staining within intact cells.
