| 产品介绍 |
RNA 上样缓冲液可用作 RNA 电泳的示踪染料。RNA 上样染料带轻微的负电荷,并且与 RNA 同向迁移,使得用户可以监测 RNA 分子在凝胶中移动的进程。凝胶组成不同,迁移速度也不一样。以 1:3 至 1:6 稀释样品,加热至 65℃,持续 10 分钟,上样前置于冰上冷却。 推荐用法:将 1 个体积的样品加入 2 至 5 倍的样品上样缓冲液中,混合均匀。将样品加热至 65°C,10 分钟,然后,在进行凝胶上样之前立刻在冰上冷却。 应用 适合与甲醛琼脂糖凝胶一起用于 Northern 印迹实验。RNA 样品上样缓冲液已被用作 Northern 印迹中的样品上样缓冲液。RNA 样品上样缓冲液特别适用于在甲醛-琼脂糖凝胶(含有或不含溴化乙锭)上进行 RNA 电泳。在 Northern 印迹检测之前,不推荐使用溴化乙锭进行凝胶染色,因为琼脂糖凝胶或上样缓冲液中存在溴化乙锭会导致转移效率低下。 适用性 原理 制备说明 外形 重悬 组分 去离子甲酰胺 62.5%(v/v)、甲醛 1.14M、溴酚蓝 μg/mL、二甲苯氰基 200 μg/mL、MOPS-EDTA-乙酸钠、1.25× 工作浓度。RNA 上样缓冲液含有 62.5% 去离子甲酰胺,1.14M 甲醛,200μg/ml 溴酚蓝,200 μg/ml 二甲苯氰基,以及 50 μg/ml 溴化乙锭,溶解在 MOPS-EDTA-乙酸钠溶液中(1.25x 工作浓度 )。 RNA loading buffer is used as a tracking dye during RNA electrophoresis. The RNA loading dye has a slight negative charge and will migrate the same direction as RNA, allowing the user to monitor the progress of molecules moving through the gel. The rate of migration varies with gel composition. Dilute 1:3 to 1:6 with sample, heat to 65C for ten minutes and chill on ice before loading.RNA sample loading buffer is especially formulated for electrophoresis of RNA on formaldehyde-agarose gels with or without ethidium bromide. Ethidium bromide is not recommended for gel staining prior to Northern blot detection because the presence of ethidium bromide in agarose gels or the loading buffer can cause poor transfer efficiency.Suitable for use with formaldehyde-agarose gels used in Northern blotting procedures.RNA Sample Loading Buffer has been used as a sample loading buffer in northern blot. |
