Raman spectrum data of human induced pluripotent stem cells at -150 deg, the temperature commonly used for the long-term storage of cells. The spectrum includes Raman signals derived from DMSO, cytochromes, and lipid and protein. The peak areas of DMSO and cytochromes were normalized to the peak area of the CH signal at 1,447 cm^{-1}.
