YeaRed是一种独特的油性大分子,不能穿透细胞膜进入细胞内。不易挥发升华,人体不会吸入。艾姆斯氏测试结果也表明YeaRed在凝胶染色浓度下完全无诱变性,是一种安全无毒的核酸染料。YeaRed与EB具有相同的光谱特性,无需改变滤光片及观察装置(普通紫外凝胶透射仪),在300 nm处紫外光激发检测即可。YeaRed适用于琼脂糖和聚丙烯酰胺凝胶电泳中的dsDNA,ssDNA以及RNA染色,可以选择胶染法或泡染法进行染色,使用非常方便、灵活。
- 安全无毒:艾姆斯氏试验结果表明,YeaRed在凝胶染色浓度下无致癌毒性
- 灵敏度高:与EB灵敏度相当,能进行高效的电泳染色
- 稳定性强:常温保质期5年
- 适用性广:琼脂糖凝胶或聚丙烯酰胺凝胶电泳前后的染色均适用
- 通用型强:与EB有相同的光谱特性,无需改变滤光性能展示
- 容易处理:废弃的YeaRed在环境下会自然分解,无需特殊处理
- 核酸染料YeaRed与EB进行琼脂糖凝胶电泳的效果对比
