“…The most significant changes reflected by Raman bands arise from nucleic acids/nucleic bases at 787, 920, 1205, 1235, 1342 cm -1 . The intense bands at 1342 and 1380 cm -1 are due to guanine vibrations, and the 1380 cm -1 band comes from vibrations of both adenine and thymine 46 . In general, the comparison of averaged Raman spectra of the ER area indicates a trend for increased protein signal.…”
