Opis ogólny
The ApopTag Fluorescein In Situ Apoptosis Detection Kit detects apoptotic cells in situ by the indirect TUNEL method, utilizing an anti-digoxigenin antibody that is conjugated to a Fluorescein reporter molecule. It provides indirect immunofluorescence staining for 40 samples. Results are analyzed using either flow cytometry or fluorescence microscopy.
The ApopTag Fluorescein In Situ Apoptosis Detection Kit has been tested for specific staining in these model systems: (a) human normal peripheral blood lymphocytes induced with dexamethasone as stained in cytospins, (b) rat regressing mammary gland as stained in formalin-fixed, paraffin-embedded sections, and (c) human leukemic peripheral blood lymphocytes induced with camptothecin, as stained in cell suspensions and used for quantitative flow cytometry.

INTRODUCTION
ApopTag In Situ Apoptosis Detection Kits label apoptotic cells in research samples by modifying genomic DNA utilizing terminal deoxynucleotidyl transferase (TdT) for detection of positive cells by specific staining. This manual contains information and protocols for the ApopTag Fluorescein In Situ Apoptosis Detection Kit (Catalog number S7110).
Principles of the Procedure
The reagents provided in all ApopTag Kits are designed to label the free 3′OH DNA termini in situ with chemically labeled and unlabeled nucleotides. The nucleotides contained in the Reaction Buffer are enzymatically added to the DNA by terminal deoxynucleotidyl transferase (TdT) (13, 31). TdT catalyzes a template-independent addition of nucleotide triphosphates to the 3′-OH ends of double-stranded or single-stranded DNA. The incorporated nucleotides form an oligomer composed of digoxigenin nucleotide and unlabeled nucleotide in a random sequence. The ratio of labeled to unlabeled nucleotide in ApopTag Kits is optimized to promote anti-digoxigenin antibody binding, or to minimize fluorescein self-quenching. The exact length of the oligomer added has not been measured.
DNA fragments which have been labeled with the digoxigenin-nucleotide are then allowed to bind an anti-digoxigenin antibody that is conjugated to fluorescein (Figure 1A). Fluorescent antibodies provide sensitive detection in immunohistochemistry or immunocytochemistry (i.e. on tissue or cells) and are not subject to experimental variations due to the substrate or the development step. This mixed molecular biological-histochemical systems allows for sensitive and specific staining of very high concentrations of 3′-OH ends that are localized in apoptotic bodies.The ApopTag system differs significantly from previously described in situ labeling techniques for apoptosis (13, 16, 38, 46), in which avidin binding to cellular biotin can be a source of error. The digoxigenin/anti-digoxigenin system has been found to be equally sensitive to avidin/biotin systems (22). Immunochemically-similar ligands for binding of the anti-digoxigenin antibody are generally insignificant in animal tissues, ensuring low background staining. Affinity purified sheep polyclonal antibody is the specific anti-digoxigenin reagent used in ApopTag Kits and exhibits <1% cross-reactivity with the major vertebrate steroids. In addition, the Fc portion of this antibody has been removed by proteolytic digestion to eliminate any non-specific adsorption to cellular Fc receptors.
