| Determining Binding Constants of Polyethylene glycol (PEG) derivatized vancomycin (Van) species and D-Ala-D-Ala terminus peptides using affinity capillary electrophoresis (ACE). In these experiments a series of Van-PEG (PEG-550, 750, 1100, 2000, 5000, and 8000 g/mol) species were synthesized. Utilizing ACE, a plug of Van-PEG and non-interacting standards are injected and electrophoresed. Analysis of the binding constant (Kb) demonstrate that derivatization of Van has little effect on the affinity of D-Ala-D-Ala peptide for Van. The findings help quantify the efficacy of PEG as a drug delivery system for glycopeptide antibiotics |
