General description
Surfactants, possessing both hydrophilic and hydrophobic components, fall into two main categories: ionic, which ionize in water (anionic, cationic, or ampholytic), and nonionic, which do not ionize. The discussed product is a nonionic surfactant with diverse applications such as emulsification, dispersion, solubilization, and detergent use. Additionally, it can serve as a solubilizer for membrane proteins.
Application
- washing buffer and blocking buffer in Western blotting
- blocking buffer in immunohistochemistry
- washing buffer in ELISA (enzyme linked immunosorbent assay)
- reaction mixture in PCR (polymerase chain reaction)
TWEEN 20 has been used as a blocking agent for membrane based immunoassays at a typical concentration of 0.05%. TWEEN 20 can be used for lysing mammalian cells at a concentration of 0.005 to 0.5%.
Features and Benefits
- Highly versatile surfactant for your life science and biochemical research
- Excellent solubilising, dispersing and emulsifying agent
- Suitable for DNA & RNA extraction, mammalian cell culture, and protein purification
Packaging
Each kit contains 3 x 100ML samples, each sample from a uniquely manufactured lot.
