To determine whether recombinant human alpha-galactosidase A effectively removes alpha-Gal epitopes from porcine aortic valve and pericardial tissues as a cost-effective alternative to plant-derived enzymes.
Treated fresh porcine aortic valve and pericardial tissue samples with consecutive concentrations of recombinant human alpha-galactosidase A.
Assessed epitope reduction via Griffonia simplicifolia type I isolectin B4 indirect immunoperoxidase avidin-biotin staining.
Recombinant human alpha-galactosidase A successfully eliminated cell-surface alpha-Gal epitopes on porcine aortic valve and pericardial tissues.
Epitope removal achieved by the recombinant human enzyme was qualitatively equivalent to the clearance achieved with green coffee bean alpha-galactosidase.

Implication

Laboratory evaluation demonstrates effective clearance of alpha-Gal epitopes from porcine valve tissues via recombinant alpha-galactosidase A, suggesting a cost-effective strategy for xenografts.
