Quick Cell Proliferation Colorimetric Assay for IC50 and IC75 concentration values of the NDV AF2240 virus strain against MDA-MB-231 cells at 24, 48, and 72 hours after treatment. As indicated, the growth rates for the treated cells decreased significantly as compared with the control cells (P < 0.05). However, no significant different (P > 0.05) was observed between the two-virus concentrations.
