TACS 2 TdT-DAB In Situ Apoptosis Detection Kit

The TACS 2 TdT DAB Kit utilizes a cation optimization system to enhance the in situ detection of apoptosis in a TUNEL based assay within fixed frozen, paraffin embedded, or plastic embedded cells and tissues. Enzymatic incorporation of biotinylated nucleotides in fragmented DNA is performed by a highly purified form of the TdT enzyme in a non-toxic labeling buffer (sodium cacodylate free). Biotin labeling is detected using streptavidin-horseradish peroxidase, and colorimetric substrates diaminobenzidine (DAB). Samples are counterstained with Methyl Green offering a nice contrast when visualized by light microscopy.

This complete kit provides all the reagents required for labeling including two permeabilization reagents, labeling and detection reagents, stop buffers, counterstain, and TACS-Nuclease reagents for generating positive controls with your own samples.
