  3. Part i this paper has minutely studied the interaction between ag ( i ) and serum albumin. the binding of ag ( i ) to human serum albumin ( hsa ) or bovine serum albumin ( bsa ) has been studied by equilibrium dialysis at ph ( 5. 4 ). the scatchard analysis indicates that there exists several strong binding sites of ag ( i ) in both hsa and bsa. a notable hysteretic effect has been observed in the interaction of ag ( i ) with hsa or bsa using uv - visible spectrometry at ph ( 5. 4 ), which shows that the binding between ag ( i ) with hsa or bsa may induce a slow transition of hsa or bsa from the conformation of weaker affinity for ag ( i ) to one of stronger affinity ( a - b transition ). the rate constants and activation parameters of this transition parameters of this tansition were measured and discussed. the binding equilibrium has been also studied by resonance light - scattering spectrum ( rls ) and flurescence quenching
