Has anybody tried applying plant extracts on MCF 7 cell lines after filtering them? will it (filtering) effect the antioxidant activity present in plants?
I'm assuming a 0.22 micron filter, or something similar. So long as the active compounds are in solution and don't adsorb on the filter material, the biological activity should remain unchanged.
Filtration with certain pore size might filter some of the active compounds. In some studies ultrafiltration was used to seperate the sample with different molecular size.. So i think filtration would affect the bioactivity
