Biological Applications

The use of filtration as a sterilizing technique is becoming increasingly popular. Other sterilization techniques such as autoclaving, radioactive exposure or ethylene oxide treatment can be detrimental for the product. A dead-end filtration using 0.22 |im pore-sized membrane is considered good for sterilizing by filtration. Viruses can permeate through the membrane of 0.22 |im filter. A 0.1 |im pore-size filter is used to prepare a virus-free solution.

Filtration is also used for desalting or buffer exchange of proteins and nucleic acids, deproteiniz-ing samples, screening natural products and combinatorial products, and separation of oligonucleotide primers from nucleic acid preparations.
