A procedure for high resolution electrophoresis of isozymes of the mosquito Aedes aegypti using nonlinear (2.5%-20%) polyacrylamide gradient gel slabs is described. Crude mosquito homogenates were electrophoresed on gradient and on homogeneous (7%) polyacrylamide gels and stained for esterase (EST), isocitrate dehydrogenase (IDH) and malate dehydrogenase (MDH). The resulting zymograms were comp...

The goal of the present study was to compare the nuclear phosphoproteins of normal and thioacetamide-treated rat liver, which are nondividing tissues, with regenerating rat liver and Novikoff hepatoma, which are growing and divid ing tissues. Thioacetamide treatment was utilized to induce nucleolar hypertrophy (1, 9). With the increased resolution of the 2-dimensional elec trophoresis method, (...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...
