The aim of the present study is to evaluate the differences on FTIR spectra of the normal lung cell noncancerous mice lung epithelial cell line e10 due to different fixation protocols for histological processing. The results shown that formalin and methacarn normally used in fixation did cause many changes on the FTIR spectra of mice lung cells e10, mainly in the organic compounds 800–1800 cm

in lipids, DNA, and proteins, and the alcohol 70% fixation protocol caused almost no changes on the FTIR spectra compared to unfixed cells spectra in PBS. It can be concluded that histological processing with alcohol 70% fixation protocol can be used in the FTIR study of mice lung cell line e10.
