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
- As an emulsifying agent for the preparation of stable oil-in-water emulsions
- In pre-extraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins)
- As a blocking agent for membrane based immunoassays at a typical concentration of 0.05%
- For lysing mammalian cells at a concentration of 0.005 to 0.5%
- Along with PBS in the dilution of antibodies in immunohistochemistry technique
- For washing cells in FISH (Fluorescence in situ hybridization) technique
Features and Benefits
- Highly versatile surfactant for your Life Science and Biochemical research
- Suitable for sensitive molecular biology research applications
- Tested for Endonuclease, exonuclease and Rnase′s
- Excellent solubilising, dispersing and emulsifying agent
