FD Apop™ Kit

FD Apop™ Kit is designed for the microscopic detection of cells undergoing apoptosis based on the principle of in situ DNA nick-end labeling (TUNEL) technique. The assay uses terminal deoxynucleotidyl transferase to catalyze the incorporation of biotinylated deoxyuridines onto the free 3′-hydroxyl termini of DNA fragments, which are considered one of the most characteristic features of apoptosis. The integrated biotins are amplified and visualized with the avidin-biotin-complex (ABC) method, enabling light microscopic identification. The reagents and procedure of FD Apop™ Kit have been optimized to achieve a high degree of both specificity and sensitivity for detecting apoptotic cells with minimal background. This kit can be used with frozen and paraffin sections, as well as cultured cells. The procedure of the kit takes approximately 4 hours.
