Abstract

The spectrophotonietric titration of the IXc-bilirubiii aqueous solution with the rat brain neuronal (synaptosomal) enthrane particles aqueous suspension (p1120o 7,2) is followed. by the transformation of the original free bilirubin aqueous solution absorptionspectram of visible light (single maximum at 440 nih and. slight shoulder in the region of 410-k20 nra) into membrane.-bound bilirubin aqueous suspension spectrum (two maxima in the region Qf '4-60 and 500 mm, respectively). As a result of the bilirubin molecules binding with membrane particles very weak origial fluorescence of the free bile pigment turns lfltO somemore fluorescence of the membrane bound. bilid.iene in the aqueous medium (the excitation and. the emission maxima are at 430 and. 520 nra ,respectively).
