Daim Ntawv Thov

Fluorescein Sodium yog siv los ua fluorescent tracer los kawm txog qhov permeability ntawm cov ntshav-lub hlwb barrier (BBB) thiab cov ntshav-lub hlwb barrier (BSCB) hauv cov qauv nas. Siv cov xim no ua ib qho probe substrate, kev thauj tshuaj ntawm lub siab cell mediated los ntawm organic anion transport peptide (OATP) tau kawm.
