FIG. 9A is a western blot on whole-cell lysates from MDA-MB-435 tumor cells stably expressing shRNA for p32 or a base mismatch control shRNA (top). Flow cytometry analysis of the same cell lines for surface levels of p32 using polyclonal anti-full-length/NH2-terminal p32 or IgG isotype control (bottom); FIG. 9B shows that TAMRA-labeled tandem peptides bearing the LyP-1 homing domain or a control domain (ARALPSQRSR, (SEQ ID NO: 1) ARAL) were incubated over p32 shRNA cells.
