FD NeuroApop Kit
NDT102 FD NeuroApopTM Kit
- Price: $663 (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.
Detection of apoptotic neurons with FD NeuroApop™ Kit. Paraffin section (10µm) cut from a dorsal ganglion of a mouse embryo (E17). The section was processed with FD NeuroApop™ kit and counterstained with methyl green (Sections courtesy of Drs. Michael Vogel and Lisa Qiu).
Detection of apoptotic neurons with NDT102 Kit. Paraffin section (10um) cut from a dorsal ganglion of a mouse embryo (E17). The section was processed with the kit and counterstained with methyl green (Sections courtesy of Drs. Michael Vogel and Lisa Qiu).
Detection of apoptotic neurons in a rat model of stroke. 20 um 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 methyl green (see below)
