Gelite Safe核酸凝胶染料* 10,000X DMS

Gelite Safe 核酸凝胶染料是一种非常敏感且稳定的荧光染料，可用于电泳凝胶中的DNA检测。 与高毒性的溴化乙锭（EtBr）不同，Gelite Safe经过专门设计，具有较低的危害性，无细胞毒性和诱变性，与EtBr和SYBR®Safe相比，具有更高的灵敏度和更低的背景荧光。 Gelite Safe的独特光谱特性扩展了其仪器兼容性，包括紫外和蓝光透射仪，凝胶记录系统和激光扫描仪。无需繁杂的操作，可在在绿色或红色通道中进行检测。，为您提供优质的Gelite Safe核酸凝胶染料* 10,000X DMSO溶液*。

样品实验方案

工作溶液配制

Gelite Safe 工作溶液

在7.5-8.5的pH范围内使用（例如，TAE、TBE或TE pH 8.2）缓冲液稀释10,000X储备试剂来制备1X Gelite Safe工作溶液。
注意：在水中配制的染色溶液比在缓冲液中配制的溶液不稳定，必须在24小时内使用。

 

后染色方案
1.根据您的标准方案运行凝胶。
2.将凝胶放在合适的聚丙烯容器中。 轻轻加入足量的1X染色溶液以浸没凝胶。
注意：请勿使用玻璃容器，因为它会吸收染色溶液中的许多染料。
3.在室温下避光轻轻搅拌凝胶约30至60分钟。
4.使用300 nm / 254 nm紫外透射仪或使用长距离绿色滤光片（例如SYBR®滤光片，GelStar®滤光片，GelGreen®滤光片或GelRed®滤光片）的凝胶扫描仪对凝胶成像。

 

预染色方案
1.使用标准方案准备琼脂糖凝胶溶液。
2.在倒入凝胶之前，将10,000X Gelite Safe储备试剂以1：10,000的比例稀释到凝胶溶液中并彻底混合。
3.根据您的标准方案运行凝胶。
4.使用300 nm / 254 nm紫外透射仪或使用长距离绿色滤光片（例如SYBR®滤光片，GelStar®滤光片，GelGreen®滤光片或GelRed®滤光片）的凝胶扫描仪对凝胶成像。
