Transformation of the gene for hypoxanthine phosphoribosyltransferase
Somatic Cell Genetics, 1979Purified DNA from wild-type Chinese ovary (CHO) cells has been used to transform three hypoxanthine phosphoribosyltransferase (HPRT) deficient murine cell mutants to the enzyme positive state. Transformants appeared at an overall frequency of 5 x 10(-8) colonies/treated cell and expressed CHO HPRT activity as determined by electrophoresis.

Facilitated Purification of Hypoxanthine Phosphoribosyltransferase
Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1976Three major approaches to the complete purification of hypoxanthine phosphoribosyltransferase from human erythrocytes and rat brain are described. Preparative isoelectric focusing which has been used for the isolation of the human enzyme was not fully successful in the case of rat brain.
