METHOD FOR RETROVIRUS REMOVAL

摘要

PROBLEM TO BE SOLVED: To provide a method for removing retroviruses from liquid samples, and a nanofiber containing liquid filtration medium that simultaneously exhibits high liquid permeability and high microorganism retention.SOLUTION: Retroviruses are removed from a liquid by passing the liquid through a porous nanofiber containing filtration medium having a retrovirus Log Reduction Value (LRV) greater than about 6, a porosity from about 80% to about 95%, and a liquid permeability greater than about 100 LMH/psi. The nanofiber has a diameter from about 10 nm to about 100 nm.
