Fig. 1From: Characterization of ovarian cancer cells and tissues by Fourier transform infrared spectroscopyRepresentative FTIR spectra of ovarian cancer cells and normal cells. FTIR spectra of the five ovarian cancer cell lines (IGROV1, A2780, ES2, SKOV3 and OVCAR3) and the normal human ovarian surface epithelial cell line (HOSEpiC) were presented in the region 4000–600 cm− 1. The apparent differences were indicated in blue boxBack to article page
