Serum containing flavonoids from the stems and leaves of Scutellaria baicalensis Georgi (SSF) diminishes potassium cyanide (KCN)-induced DNA fragmentations in neuronal nuclei.
The primary cortical neurons were treated with 1 mmol/L KCN for 60 minutes with or without 75.92 μg/mL SSF. Fragmented DNA was isolated by NucleoBond DNA and RNA purification kits, electrophoresed with agarose gel, and finally stained with ethidium bromide.
