Table 2. Serum albumin adsorption.

Type of surface	SA	CA	SOI
BSA (OD) (n=9)	0.281±0.006	1.120±0.024a)	1.287±0.040a)
FITC-labeled BSA (pixels) (n=3)	3,972±607	1,599,268±119,340	3,102,829±72,992

Values are presented as mean±standard deviation.

SA: conventional sandblasted, large-grit, acid-etched surface, CA: sandblasted, large-grit, acid-etched surface in calcium chloride aqueous solution; SOI: sandblasted, large-grit, acid-etched surface coated with pH buffering solution, OD: optical density, FITC: fluorescein isothiocyanate, BSA: bovine serum albumin.
