In vivo electroporation is an efficient means of increasing plasmid DNA delivery to normal tissues, such as skin and muscle, as well as directly to tumors. In the experiments described here, plasmid DNA was delivered by in vivo electroporation to B16 mouse melanomas using two very different pulsing protocols. Reporter expression increased 21- or 42-fold, respectively with electroporation over injection alone. The growth of experimental melanomas with an approximate diameter of 4 mm on the day of treatment was monitored after electroporation delivery of reporter plasmid DNA. Remarkably, short-term complete regressions using one of these pulsing protocols occurred in up …

Fluorescence in situ hybridization (FISH) permits the detection of unique DNA sequences of target DNA within single cells. FISH allows the identification of DNA sequences within individual cells and readily identifies genetic changes within a mixed population of cells. However, problems arise in maintaining nuclear morphology, particularly following harsh denaturation procedures where cells are heated to 80°C, causing the nuclear boundary to become blurred or the cell to completely burst. In an attempt to preserve cellular morphology and high hybridization efficiency, particularly in fresh tissue samples, we evaluated a FISH protocol using alkaline denaturation in place of heat.
