From: Bacterial delivery of the anti-tumor azurin-like protein Laz to glioblastoma cells
Cytotoxic effect of the purified Laz on tumor cells in vitro. Monolayer of MCF-7 Breast cancer cell line and glioblastoma cell lines U-373 and LN-229 were incubated with increasing concentrations (0.1, 1, 5 μg ml−1) of purified Laz protein or a control protein (Ovalbumin) for 24 h. Apoptotic activity was assessed with respect to the control group at the same concentration *P < 0.0001
