Tween
Tween 20 and Tween 80, members of the polysorbate family, stand out as nonionic detergents that have been extensively researched for their wide-ranging applications in molecular biology. These surfactants feature an amphipathic structure composed of polyoxyethylene sorbitan fatty acid esters, which imparts them with remarkable solubilizing properties. The unique structure of Tweens has made them instrumental in studies focusing on protein solubilization, demonstrating compatibility across diverse biological samples.
The versatility of Tweens is prominently showcased in their role as blocking agents in immunoassays, where they play a crucial role in minimizing nonspecific interactions. Their mild nature and minimal impact on protein structure make them indispensable in various techniques, including enzyme-linked immunosorbent assays (ELISAs) and immunoblotting. Additionally, Tweens find utility in cell and tissue culture, aiding in the maintenance of cell viability and the prevention of cell clumping.
The extensive research on Tween 20 and Tween 80 underscores their importance as essential tools in the molecular biology toolkit, contributing to advancements in experimental methodologies and ensuring reliable results in a range of biological applications.
