Allgemeine Beschreibung
Allows for detection of apoptosis at the individual cell level. Apoptosis morphology is easily detected. Detection is by flow cytometry or fluorescence microscopy. The kit mounting media permits the observance of the total cell population.
Cat. No. QIA39 is a fluorescein-conjugated version of our widely referenced TdT Colorimetric FragEL DNA Fragmentation Detection Kit (Cat. No. QIA33) for non-isotopic labeling. Terminal deoxynucleotidyl transferase (TdT) binds to exposed 3′-OH ends of DNA fragments generated in response to apoptotic signals and catalyzes the addition of fluorescein-labeled and unlabeled deoxynucleotides. When excited, fluorescein generates an intense signal which can be detected by fluorescence microscopy or flow cytometry. The mounting media sustains the fluorescent signal from samples labeled on slides and, therefore, aids in the morphological evaluation and characterization of normal and apoptotic cells. Non-apoptotic cells can be visualized by a DAPI filter.
Komponenten
Proteinase K, Equilibration and Labeling Buffers, TdT Enzyme (Cat. No. PF060), Control Slides, Mounting Media (Cat. No. HC08), and a user protocol.

Prinzip
The Calbiochem Fluorescein-FragEL DNA Fragmentation Detection Kit is a non-isotopic system for the labeling of DNA breaks in apoptotic nuclei in paraffin-embedded tissue sections, tissue cryosections, in cell preparations fixed on slides, or in cell suspensions. Detection and analysis of labeling is possible by flow cytometry or fluorescence microscopy.
Lagerung und Haltbarkeit
Fluorescein-FragEL kit components are shipped on dry ice. Upon receipt, store kit at -20°C in a non-frost-free freezer. To avoid reagent loss in tube caps, briefly pulse spin all thawed solutions before removing caps. (see General Considerations below).
