Static adhesion of platelets to peptides derived from bovine α1(III)CB4 fragment. Human washed platelets adhered only to peptide p8 derived from α1(III)CB4 fragment. This binding was abolished by the anti-GpVI single chain antibody 10B12 (20 μg/mL). Data are the mean plus or minus SE (n = 2-16) for absorbance values at 405 nm.
