- Low protein binding minimizes nonspecific protein adsorption
- Hydrophilic membrane suitable for aqueous applications, especially in alkaline pH
- Smooth surface for easy enumeration of microorganisms
Tissue culture applications often require a sterile membrane that exhibits low protein binding, which allows for an approximation of in vivo conditions under which the cells would normally be found.
PES membrane filters provide a smooth membrane to retain and enumerate microorganisms on the filter surface. The white surface allows easy counting of dark bacteria and artifacts in a variety of microbiology studies.
Low protein binding PES membranes with low levels of extractables are appropriate for tissue culture applications after they are sterilised.
