Table 2.

Viable cell counts for cells treated with either 2B12 or an irrelevant IgG, both at 10μg/ml, expressed as a percentage of cell counts of controls (growth media alone). Counts were performed after incubations lasting from 3 hours to 6 days. No significant differences (p<0.05) from control were detected in two-tailed Student’s t tests, n=3-4.
