The water relaxation enhancement behavior of GdDTPA in human serum albumin
(HSA) solution has been studied. The results indicate that GdDTPA can integ
rate noncovalently with HSA, mainly in forms of (GdDTPA)HSA and (GdDTPA),HS
A, for which the apparent equilibrium constants are 0.05 mM(-1) and 0.02 mM
(-2), respectively. (C) 1999 Elsevier Science Ltd. All rights reserved.
