title: Binding of taurine to brain synaptic membranes.
abstract: An account is given of our endeavours to demonstrate sodium-independent and -dependent taurine binding to brain synaptic membranes. The total and specific sodium-dependent binding and the total sodium-independent binding were fairly easily amenable to characterization, but the disclosure of specific sodium-independent binding succeeded only after repeated freezing and thawing, thorough buffer washes and two Triton X-100 treatments of the membranes. The sodium-independent binding capacity for taurine was rather small and only one type of relatively low-affinity binding site was revealed.
