 <td style="margin: 0px; border: 0px rgb(0, 0, 0); background-color: transparent;" colspan="4">溴化乙锭是一种高度灵敏的荧光染色剂，用于观察琼脂糖和聚丙烯酰胺凝胶中的DNA。溴化乙锭用标准302nm紫外光透射仪激发并放射出橙红色信号，可用Polaroid底片或带CCD成像头的凝胶成像处理系统拍摄。对于在电泳后进行凝胶染色，应先用水将储存液样品稀释到0.5μg/ml，再将凝胶孵育15-30分钟。通常无需脱色，但是如果必须降低背景色，则可在水中脱色15分钟。然后可在紫外灯箱（254nm波长）中检测DNA条带。也可将溴化乙啶加到凝胶和电泳缓冲液（终浓度0.5μg/ml）中，并在电泳后立即显影。</td>
