title: Quantitation of metabolic cooperation by measurement of HGPRTase activity.
abstract: A method for the quantitation of metabolic cooperation between cells is described. The method depends upon measuring the increase in HGPRTase activity that occurs between HGPRT+ cells and the HGPRT-LN (Lesch-Nyhan) cells. The variables upon which this method depends and their effect on the final determination are discussed.
