Protein Concentration (Low Binding)-Sterile Filtration
Serum-free media and buffers are typically not as challenging to filter as serum-containing media. However, it is common for protein concentrations to be very low in these solutions. With this in mind, it is very important to choose a low protein-binding syringe filter. Binding is the property of substances to have an affinity for filter media or other filter components. When filtering solutions with low protein concentrations, certain filters can lead to the loss of active proteinaceous ingredients. To minimize protein loss during filtration of proteinaceous solutions, choose products with Pall's Supor membrane:
