Embodiment

[0017]Unless otherwise specified, the experimental methods used in the examples are all conventional methods. Unless otherwise specified, the materials and reagents used in the examples can be obtained from commercial sources.

[0018]Reagent

[0019]PBS buffer (10mM, pH 7.4): NaH2PO4 0.24g / L, Na2HPO4 1.42g / L, KCl 0.2g / L and NaCl 8.0g / L, the solvent is water.

[0020]Strain information of influenza virus

[0021]Strain A / PR8 / 8 / 34 (H1N1): referred to as PR8, literature: C-T. Guo et al. Glycobiology 2007, 17, 713-724.

[0022]Acquisition of influenza virus

[0023]Prepare 9-10 day-old SPF chicken embryos, and mark the embryonic chicken air chambers with an egg finder. Use a thin iron wire or a needle to make a hole in the air chamber and at the same time make a hole in the middle of the chicken embryo where there is no blood vessel. Inoculate an appropriate amount of influenza virus seed into 9-10 day old chicken embryos, and seal the punched area with wax. Cultivate in a 37°C incubator, observe the va...

Abstract

The invention relates to application of carboxylic acid type cation exchange fibers in adsorbing and / or filtering influenza viruses. In the aspect, the invention also relates to the carboxylic acid type cation exchange fibers as a prevention and control material for preventing human or livestock avian influenza virus infection, such as an air cleaning filter material, a mask and the like.

Description

Technical field[0001]The invention belongs to the application field of functional fibers, and specifically relates to the use of carboxylic acid type cation exchange fibers and their fabrics in adsorbing and / or filtering influenza viruses.Background technique[0002]Influenza (flu) is an acute zoonotic disease caused by influenza viruses. Its host involves humans, pigs, birds, horses, dolphins and other animals. Influenza viruses can be spread through droplets in the air, contact between susceptible and infected persons, or contact with contaminated items. Influenza viruses have high spread and rapid variability, which not only seriously threaten human health, but also cause major economic losses. Therefore, the prevention and control of influenza virus is always an important and urgent problem to be solved.[0003]Since the 1960s, people have known that certain positive (negative) charged ion exchange materials have the function of enriching, filtering or purifying viruses and microorg...
