To create DNA ladders of superior quality, each fragment is purified individually using proprietary SYBR Safe stain is specifically formulated to be lesschromatography-based technology. Our DNA ladders are hazardous than ethidium bromide and reduces yourstable during prolonged storage at room temperature and exposure to UV light.
