RESUMO
Histopaque-1119 (Sigma Chemical Co., St. Louis, Mo.) and Plasmagel (Cellular Products, Inc., Buffalo, N.Y.) were compared as density gradient separation reagents for the separation of polymorphonuclear leukocytes and mononuclear cells from blood from the isolation of cytomegalovirus (CMV). Of 200 peripheral blood specimens examined, CMV was recovered from 51 by both methods. The time of detection of immunofluorescent sites or a cytopathic effect associated with CMV was similar by each method. The Histopaque-1119 method was less time-consuming than the Plasmagel method since it did not require a precentrifugation step for the settling of erythrocytes. The use of Histopaque-1119 will permit an effective alternative single-step method for the separation of blood leukocytes for the isolation of CMV.
