Reduction factor for protein adsorption by a pre-adsorbed C3M-PAPEO₁₄/P2MVPI₄₃ (f- = 0.5) layer on silica (a) and polystyrene (b). Concentrations of proteins and grafted block C3Ms in solutions were 100 mg/l. pH 7 ± 0.1. Symbols: inverted filled triangle β-lac, filled square BSA, filled diamond Lsz. Lines were added to guide the eye. Results for the reduction of β-lac adsorption on C3M-PAPEO₁₄/P2MVPI₄₃ (f- = 0.5) layer are not included in the graph. Due to the effect this protein has on the coating, it is not possible to quantitatively determine the reduction factor for its adsorption
