Thrombin and albumin adsorption to PVA and heparin-PVA hydrogels. 2: Competition and displacement.


Thrombin adsorption to polyvinyl alcohol (PVA) was different from its adsorption to polyethylene (PE)--not so much in amount, but in its affinity. Thrombin was more easily displaced from polyethylene and its adsorption was more readily prevented by prior or simultaneous exposure to albumin. From PVA (or heparin-PVA), only approximately 30% of the adsorbed… (More)
