General description
Surfactants, characterized by hydrophilic and hydrophobic elements, are broadly classified as either ionic (anionic, cationic, or ampholytic) or nonionic, depending on their ionization behavior in water. The specific product in question falls into the nonionic category and finds versatile applications, including emulsification, dispersion, solubilization, and as a detergent. Notably, it can also act as a solubilizer for membrane proteins.
Application
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
- BioXtra grade for your sensitive applications
- Tested for trace levels of Anions and Cations
- Excellent solubilizing, dispersing, and emulsifying agent
- Suitable for mammalian cell culture, protein purification, and hybridization studies
