Cells of the LNCaP series express cell-surface RHAMM in the absence of CD44.

<p>Western blotting and densitometry for RHAMM (A) and western blotting for CD44 (B) across the LNCaP series of cell lines with β-actin used as a load control. Cell surface biotinylation for RHAMM and CD44 with GAPDH utilized as a cytoplasmic control (C). PC-3 lysate was used as a positive control for CD44, Error bars = SEM, n = 3, *p<0.05 compared to LNCaP.
