网页2019/08/20 · The membrane filter principle is the screening process. The raw material liquid passes through a microporous membrane material to separate specific substances under the action of static pressure difference. Microfiltration is also called a microporous filtration membrane. The principle of membrane filtration uses a membrane with selective
网页2019/04/16 · Membrane filtration method is a method of measuring the radioactivity in antigen-antibody complexes by using the characteristic of microporous membranes to better adsorb proteins and allow small molecule antigens to filter through. The membrane is a solid phase method. Used to separate immune complexes from free antibodies or antigens.
