Table 1 Concentrations of various VAPs and MLI that are able to inhibit the growth of MFM-223, KPL-1, HCC-1937 and MCF-7 breast carcinoma cell lines by 50 % (IC50 values).

From: Mistletoe lectin is not the only cytotoxic component in fermented preparations of Viscum album from white fir (Abies pectinata)
