A simple method for the determination of the proportion of true GABA within labeled "GABA" used for membrane binding assay is presented. The method is intended for the assessment of the integrity of refrigerator (+4 degrees C) stored labeled neurotransmitter. Its application allows a precise determination of the binding parameters.
