Spectrometric Study of the Interaction between Azur A and Biological Macromolecules

GAO Guizhen, ZHANG Xingtao, YUAN Weifeng (Department of Biochemistry,Suzhou University,Suzhou,Anhui,234000,China)  
The absorption spectras of the interaction between the spectroscopic probes Azur A(AA) and the biological macromolecules(sulfation pachymaran(SP),chondroitin sulfate(CS),hyaluronic acid(HA),etc) are comparatively studied by spectrometry.The mechanism of the interaction and function group between the biological macromolecules and the Azur A is also discussed.And the maximum binding numbers of AA-SP and AA-CS are obtained,which are 62 and 151.The results show that AA can interact with both sulfate group and carboxylic group of the biological macromolecules.
