Introduction

The product is the core raw material for nucleic acid extraction after strict screening and quality control. Tween-20 is a non-ionic surfactant with hydrophilic end and hydrophobic end. On the one hand, it does not dissociate in water and has high stability in solution. Tween-20 is a polysorbate surfactant with fatty acid ester group and long polyoxyethylene chain. Their critical micelle concentration is very low. They are generally mild surfactants. They not only do not affect protein activity, but also have high ability to dissolve protein. Tween-20 can be used as a cosolvent for mammalian cell lysis and membrane protein. The combined action of Tween-20 / Triton X-100 is beneficial to improve the activity of protease K and extract the cleavage of lysate.
