抜粋

The recombinant fragment of the platelet membrane glycoprotein, rGPIb́, was conjugated to phospholipid vesicles with the average diameter of ca. 1 μm using N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP). We used five kinds of rGPIb́-vesicles with different fluorescent anisotropies of 1,6-diphenyl-1,3,5-hexatriene (DPH) to study the rolling properties of the vesicles on the von Willebrand factor (vWf)-immobilized surface. Under flow conditions, the rolling velocity of the rGPIb́-vesicles decreased with the increasing membrane flexibility. It is considered that the vesicles with a high membrane flexibility have a high deformability and can be flattened to a high degree during rolling on the vWf surface, thus resulting in the large contact area. We obtained a recipe to control the rolling velocity of artificial platelets by membrane flexibility.
