摘要：
Binding interactions between several vancomycin tracers and (N,N'-diacetyl)KDADA in solution were evaluated in a competition format using a surface plasmon resonance instrument. Tracers derivatized from the carboxy terminus or the N-vancosaminyl sugar moiety of vancomycin bind the peptide with an affinity similar to that of underivatized vancomycin. In contrast, N-methylleucyl derivatized vancomycin tracers bind the peptide with a reduced affinity relative to vancomycin. (C) 2000 Elsevier Science Ltd. All rights reserved.
