Tween 80 and Tween 20 Biocompatible Surfactants for Creating Percoll Density Gradients with Polyethylene Microspheres

Tween is a non-ionic viscous liquid often used as a surfactant for dispersing hydrophobic particles in aqueous solutions and as a non-ionic detergent for selective protein extraction and isolation of nuclei from mammalian cell lines. Bio-compatible surfactants, Tween 80 and Tween 20 are often used for placing polyethylene microspheres in suspension.
