Comparison of band intensity ratios between malignant (PC3) and normal cells (PNT1a) based on the weak Raman bands at 1076 cm⁻¹ and 1232 cm⁻¹.

Raman shift (cm^−1)	Raman intensities (arbitrary units)
	Stage 1		Stage 2		Stage 3		Band ratios
	PNT1a	PC3	PNT1a	PC3	PNT1a	PC3	PC3(1)/PNT1a(1)	PC3(2)/PNT1a(2)	PC3(3)/PNT1a(3)
1076	0.67	0.65	0.64	0.64	0.74	0.77	0.970	1.0	1.04
1232	0.60	0.55	0.74	0.68	0.79	0.78	0.917	0.919	0.987

The numbers 1, 2, and 3 enclosed in brackets identify the stage of cell proliferation.
