title: Enzyme activities in blood cells of man and dogs after separation on a discontinuous Percoll gradient.
abstract: From human and dog peripheral blood, thrombocytes (TRC), mononuclear cells (MNC), polymorphonuclear cells (PMNC), and red blood cells (RBC), were harvested after separation on a discontinuous Percoll gradient in a two-step centrifugation procedure, and 12 enzyme activities were determined in these highly purified cells. The enzyme activities measured are generally severalfold higher than previously reported, a fact which is attributed to the gentle and time-shortening isolation in Percoll, the cell disruption technique using detergent and the enzyme test conditions.
