General description
表面活性剂同时具有亲水和疏水成分,可以分为两大类:在水中电离的离子型(阴离子、阳离子或两性)和不电离的非离子型 。所述产品为非离子表面活性剂,可用于各种应用,如乳化、分散、增溶和去污剂。此外,它可用作膜蛋白的增溶剂。
Application
- Western blotting中的洗涤和封闭缓冲液
- 免疫组化中的封闭缓冲液
- ELISA(酶联免疫吸附测定)中的洗涤缓冲液
- PCR(聚合酶链反应)中的反应混合液
通常0.05%浓度的TWEEN 20在基于膜的免疫检测中被用作封闭剂。0.005至0.5%的TWEEN 20可用于裂解哺乳动物细胞。
Features and Benefits
- 用于生命科学和生物化学研究的多功能表面活性剂
- 良好的增溶、分散和乳化剂
- 适用于DNA & RNA 提取、哺乳动物细胞培养和蛋白质纯化
Packaging
每个试剂盒包含3 x 100ML样品,每份样品都有唯一的制造商批号。
