Figure 5.

Western blot analysis of NCAM from the proteins of UKF-NB-3, UKF-NB-4, IMR-32 (Ctrl) versus vincristine (VCR) or doxorubicin resistant subpopulations (DOX). Cell lysates were incubated with anti NCAM (clone 16.2) monoclonal antibodies, which detect the NCAM 120, 140 and 180 kDa isoform. beta-actin served as the internal control. The figure shows one representative from three separate experiments.
