Figure 3
Topographic and phase contrast images of the protein films. (a) Sample N1 (SI-L)+AP alkaline phosphatase was immobilized on the monolayer of the lipid mixture (phosphatidylcholine/cholesterol). (b) Sample N2 (SI-CAP)+AP alkaline phosphatase was immobilized on the monolayer of cellulose acetopivalinate. (c) `Uncovered' protein film: the film was deposited in much the same way as sample N2 but without the topmost cellulose acetopivalinate layer. |
