Adenosine deaminase in the pig: tissue-specific patterns and expression of the silent ADA0 allele in nucleated cells.

Abstract

By means of polyacrylamide gel and cellulose acetate enzymo-electrophoresis, the authors have studied tissue-specific isozymes of adenosine deaminase in the pig; these have been correlated to the erythrocytic ABO-like polymorphism. The enzyme product of the ADA0 gene was detected in nucleated cells; the absence of the ADA0 gene product in erythrocytes was tentatively accounted for by an increased in vivo lability.
