Quality control of [125
I]SGMIB-MNT. (a) Phosphor image of the dried SDS-PAGE gel (Any kD™ Mini-PROTEAN® TGX™ Precast Gels, Bio-Rad, CA, USA) of [125I]SGMIB-MNT. The main band at about 75 kD standard band corresponds to full-sized [125I]SGMIB-MNT (57%), while the minor band at about 150 kD (12%) is consistent with an MNT dimer. (b) [125I]SGMIB-MNT and (c) [125I]iodoEGF binding to A431 cells. (d) [125I]SGMIB-MNT and (e) [125I]iodoEGF binding to D247 MG cells. Bars represent standard error of mean.
