Human adenosine deaminase and its binding protein in normal and adenosine deaminase-deficient fibroblast cell strains
PE Daddona, MA Frohman and WN Kelley
Reduced or absent adenosine deaminase activity occurs in all tissues of
some patients with severe combined immunodeficiency disease. In this report
we describe (a) a sensitive and specific radioimmunoassay for fibroblast
adenosine deaminase and its binding protein, (b) the importance of various
tissue culture media on the expression of fibroblast adenosine deaminase,
and (c) the levels of immunoreactive adenosine deaminase compared to its
binding protein in normal and homozygous adenosine deaminase-deficient
fibroblast cell strains.
