Comparison of Folate Receptor Targeted Optical Contrast Agents for Intraoperative Molecular Imaging

HeLa and KB cells were cultured with EC17 and OTL38 to measure sensitivity for small quantities of tumor cells. For both cell lines, OTL38 had a higher SBR than EC17, particularly at the smaller quantities of cells and with lower dilutions of the fluorochromes.
