Project Title: TRANSFECTION OF CELLS WITH CATIONIC LIPOSOMES

Cultures of mouse L cells were used for transfection (the incorporation of foreign DNA into cells). Plasmid DNA encoding B-galactosidase was mixed with different types of liposomes (lipid vesicles) to increase transfection efficiency. Different concentrations of liposomes to DNA were tried as well as different transfection times. Efficiency was measured with an ONPG (o-nitrophenyl-B-D-galactopyranoside) assay (ONPC turns yellow in the presence of B-galactosidase). Many problems developed with the ONPG assay. Some of the problems were solved during the internship but several more remain to be solved before this assay can be used as an accurate and reproducible measure of transfection.
