Identification of Non-gal, Non-HLA Antigens in Patients Implanted with Xenogenic Material

Overview

About this study

The purpose of this study is to identify non-HLA and non-gal protein antigens in transplanted xenogenic tissues (ie bovine or porcine pericardial heart valves) that can then be used to preemptively identify and overcome graft-specific immune responses.
