Figure 2From: Modulation of apoptosis by V protein mumps virusApoptosis in cervical adenocarcinoma cells that express proteins VWT and VGly. At 48 h of expression, 2 h with 4000 IU/mL of IFN-α. The DeadEnd Colorimetric TUNEL System marks the fragmented DNA in situ with biotinylated nucleotides by terminal transferase rTdT. The complex was detected with streptavidin-horseradish peroxidase (HRP) using the chromogen substrate diaminobenzidine and H2O2. As a result of the procedure the nuclei are stained dark brown.Back to article page
