Table 2. Anti-EMP2 IgG1 inhibits secondary tumor formation.
The take rates of secondary tumors created from HEC1A tumors treated previously with control or anti-EMP2 IgG1 were tabulated. The extreme limiting dilution analysis (ELDA) was used to compare the frequency of cancer stem cells between the control and anti-EMP2 IgG1 treated animals48.
