Le 3) and from TCPS (Figure 2e, Table 3), but not in eluates from CH3 SAMs (Figure 2a, Table 3). Furthermore, following exposure of test materials to serum (Figures 2a to 2e, Table 3), vitronectin bands were detected at 65 kDa and 75 kDa in the eluates from all SAM surfaces implying that degradation of this protein did not occur. Taken together, these results suggest that the profiles of protein
