CYCS and cancer: Figure 4 shows thatthe Raman spectrum of cancer breast cells of HTB-30 (SK-BR-3) lineis dominated by cytochrome c. One can see that thevibrations of the heme group in cytochrome c: ν15 (750 cm–1), ν22 (1127cm–1), ν21 (1310 cm–1), and ν19 (1582 cm–1) are thestrongest bands in the cancer breast cell of HTB-30 (SK-BR-3).
