Fig. 4From: Evaluation of the theranostic potential of [64Cu]CuCl2 in glioblastoma spheroidsExpression of the copper transporter, CTR1, in T98G, U373, U87 and RA spheroids. A Western blot analysis performed to study basal expression levels of CTR1 in spheroids derived from the panel of cell lines selected. Actin was used as a loading control, and detected after stripping of the membrane. B Quantification of CTR1 relative expression in comparison to actin expressionBack to article page
