導入
- 製品の品質: The product undergoes rigorous screening and quality control processes to ensure its efficacy and reliability as the core raw material for nucleic acid extraction.
- Tween-20 Properties: Tween-20 is a non-ionic surfactant characterized by a hydrophilic end and a hydrophobic end. It maintains stability in aqueous solutions due to its non-dissociative nature and possesses a low critical micelle concentration.
- 構成: Tween-20 belongs to the polysorbate surfactant family and comprises a fatty acid ester group along with a long polyoxyethylene chain. These properties make it a mild surfactant with high protein-dissolving capabilities.
- Protein Activity: Tween-20 has minimal impact on protein activity, making it suitable for various applications where protein stability is crucial.
- 応用: It serves as a cosolvent for mammalian cell lysis and membrane protein extraction. さらに, the combination of Tween-20 with トリトンX-100 enhances the activity of protease K and facilitates the cleavage of lysates during extraction processes.
