Detection of apoptotic neurons in a rat model of stroke. 20 �gm cryostat section was cut from the rat striatum of a stroke model. The section was processed for detecting neuronal apoptosis with the kit and then counterstained with NDT methyl green (see below)

NDT102 FD NeuroApopTM Kit
Price: $498.00 (For 35 sections)

This Kit is specifically designed for the detection of neuronal apoptosis in tissue sections from the central nervous system based on the principle of in situ DNA nick-end labeling (TUNEL) technique1. 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 as one of the most characteristic features of apoptosis2, 3. The integrated biotins are amplified and visualized with the avidin-biotin-complex (ABC) method4, enabling light microscopic identification.

The reagents and procedure of the kit have been optimized to achieve a high degree of both specificity and sensitivity for detecting apoptotic neurons with the lowest background. This kit can be used with frozen5 and paraffin sections, as well as cultured cells (cf. photo samples below). The procedure of the kit takes approximately 4 hours.
