Abstract
The 3‐(4,5 dimethylthiazol‐2‐yl)‐2,5 diphenyltetrazolium bromide (MTT) assay is used successfully to estimate the number of viable cells in drug screening trials. We used the MTT assay to assess the viability of a rodent ovarian carcinoma cell line (DMBA‐OC‐1R) after exposure to combinations of cisplatin and 5‐fluorouracil as free drug and in encapsulated (conjugated and unconjugated) forms. After 48h of exposure to free drugs, a significant trend towards cell cytotoxicity could be observed and this was well established by 120h. Cells treated with drug‐containing immuno‐microspheres showed a similar initial decrease in cell viability after 96h, and this was maintained for 128h. These results suggest that immuno‐microspheres loaded with chemotherapeutic drugs have the potential to be successfully used in the treatment of ovarian cancer.
