Cytotoxicity of P1G10 fraction (IC₅₀) in normal and tumor cell lines.

Types	Cell Lines	IC50 (µg/mL)
Tumoral	B16F1	12.7
	4T1	9.1
	Ehrlich	6.9
Normal	CHO	28.7
	CIPs	16.6
	BHK-21	19.0

Cells were exposed for 72 h to increasing concentrations of P1G10, and cell viability was determined by MTT metabolism. The IC₅₀ was determined after calculating the regression of experimental data (r ≥ 0.90). Data shown are representative of three independent experiments. Tumoral cell lines: B16F1—murine nonmetastatic melanoma, 4T1 and Ehrlich—murine breast carcinomas. Normal cell lines: CHO—Chinese hamster ovary normal, CIPs—rabbit aorta endothelial cells and BHK 21—Chinese hamster kidney.
