具有DAPI的FluoroQuest 是一种水性固定介质,用于保留组织和细胞涂片的荧光。这种封固剂含有抗褪色剂以降低染料的光漂白速率,并以DAPI强化,DAPI是DNA的复染剂。用于原位杂交技术或需要荧光法进行DNA染色的其他方法。DAPI在360 nm处激发并在460 nm处发射,产生蓝色荧光。百萤生物是AAT Bioquest的中国代理商,为您提供优质的FluoroQuest 防褪色固定介质。
样品实验方案
以下是我们推荐的方案,仅提供指导。具体实验应根据您的特定需求进行修改。
- 预热溶液:从冰箱中取出安装溶液。将瓶子加热至室温,避光。
- 添加溶液:清除样品中多余的液体。向样品中加一滴固定溶液。如果样品在载玻片或组织培养皿上,请小心地将盖玻片放在液滴上,以免产生气泡。如果样品在盖玻片上,请将盖玻片倒在干净的玻璃载玻片上。去除多余的防褪色成分。
- 准备用于成像的样品:固定溶液应孵育2小时至过夜。要长期存放,请用指甲油或塑料密封剂将盖玻片密封在玻片上。已安装的载玻片应在黑暗中于4°C存放,荧光成像将保持稳定数周,样品可以在安装后立即成像。
