Relative adsorption of proteins to cell culture polystyrene.

Adsorbed Protein	Abbreviation	μg per ml
Complement C3bi	C3bi	15.8±0.8
Collagen type I	CN I	13.1±1.0
Fibrinogen	FG	24.9±0.5
Fibronectin, cellular	FNc	21.0±1.0
Fibronectin, plasma	FN	30.1±1.2
Thrombospondin	TSP	17.4±0.9
Vitronectin	VN	16.5±0.6
Von Willebrand Factor	vWF	32.2±0.7

Proteins were adsorbed from solutions of 50 μg per ml for 1 hr at 37°C. The Pierce BCA assay was performed in each well after aspirating and washing twice to remove unadsorbed proteins. Relative μg per ml were obtained using a bovine serum albumin standard curve. Values represent the means ± SEM, n = 3.
