Illustration of uremic serum incubation with different membrane materials. The serum collected from HD patients was added to an Eppendorf tube containing a small sample of membrane material (in green). The interaction took place for 30 min after which the membrane sample was removed and the serum analyzed based on fluorescence response (BioRender—GP22PBN2KN).
