The ultrafiltration tube can be reused. Soak it in 0.1M NaOH for 1-2h, wash it with water, and then wash it with relevant solution (sterilized water or PBS) on the centrifuge for 3 times, which can be

Select the appropriate ultrafiltration tube. Generally, the molecular weight to be retained should not be greater than 1 / 3 of the molecular weight of the target protein. For example, if the molecula

In the separation process of biological products, the selection of membrane materials is very important. It must meet the following requirements: low nonspecific protein adsorption

​The device is simple, the dead volume is small, and the sample processing time is fast. It can be carried out quickly from research and development to production.

The utility model relates to the field of tangential flow filtration, in particular to a tangential flow filtration system.
