In the TUNEL assay, TdT enzyme catalyzes the addition of labeled dUTP to the 3′- ends of the internucleosomal DNA strand breaks that are a hallmark of apoptosis. The CF™640R TUNEL Assay Apoptosis Detection Kit employs dUTP conjugated to the exceptionally bright and photostable CF™640R far-red fluorescent dye (Ex/Em 642/662 nm), for single step fluorescent TUNEL labeling of fixed cells or tissues for analysis by fluorescence microscopy or flow cytometry.
