Abstract

Cultured human skin fibroblasts are commonly utilized in the detection of hemizygosity and heterozygosity for hypoxanthine-guanine phosphoribosyltransferase (HGPRT) deficiency. Two obstacles are encountered in the determination of HGPRT and adenine phosphoribosyltransferase (APRT) in extracts of cultured skin fibroblasts: the sensitivity of these enzymes in dilute cell suspension to freezing and thawing (1), and the presence of nucleotidase activity (2).
