title: Transient expression of the chloramphenicol acetyltransferase gene in cultured mosquito cells.
abstract: A recombinant plasmid in which the bacterial chloramphenicol acetyltransferase (CAT) gene is under the control of the Drosophila heat-shock protein (hsp) 70 promoter has been introduced into cultured mosquito (Aedes albopictus) cells using 1,5-dimethyl-1,5-diazaundecamethylene polymethobromide (polybrene) and dimethylsulfoxide (DMSO). CAT activity was induced by incubating transfected cells at 37 degrees C, and high levels of enzyme activity were maintained for more than 24 h after the temperature shock. Transfected DNA was maintained in the cells for at least 4 days. These experiments document an effective method for introducing purified DNA into cultured mosquito cells.
