| 摘要 |
<p>The invention relates to methods for separating biological contaminants (viruses, nucleic acids and/or endotoxins) from biological products, or for reducing the content of such biological contaminants in said biological products. The sample (biological product) to be purified is treated with an anion exchanger membrane. Said anion exchanger membrane is obtained by reacting a polyamide with an aminoreactive compound which is capable of polymerisation. This is followed by polymerisation with monomers which contain cationic groups or into which cationic groups can be introduced in a reaction analogous to polymerisation.</p> |
