[Some photometric and fluorimetric characteristics of acridine orange and its complexes with glycosaminoglycans: proposed method for their spectrophotofluorimetric evaluation. 2. Spectrophotofluorimetric study].

From the present spectrofluorimetric investigation of AO and its complexes with anionic polymers, derives the possibility of a direct quantitative evaluation of GAG as such, and not through the dosage of one of their molecular components. On the other hand, the method proposed is characterized by its simplicity and rapidity. Besides, the noticeable extent of the range in which there exists a correlation between the response intensity at =640 nm and the doses of GAG considered should be stressed.
