doi: 10.1371/journal.pone.0123293
Figure Lengend Snippet: ( A ) Uptake of fluorescently-labelled proteins by CHO cells transfected with human CD36 as compared to non-transfected cells. ( B ) Binding of anti-CD36 mAb and control mouse IgA to CD36-transfected and non-transfected CHO cells, determined by cellular ELISA. ( C ) Binding of rCD36 to plate-adsorbed proteins. ( D ) Effects of 10 or 100 μg/ml of indicated, soluble ligands on rCD36 binding to plate-adsorbed OVA-Cl. ( E ) Binding of polyclonal anti-mouse CD36 Ab and control goat IgG to BM-DC, splenic DC and PEM. A representative histogram of Ab binding to BM-DC is displayed on the left graph. ( F ) Binding of anti-mouse SR-A mAb and control rat IgG2b to BM-DC, splenic DC and PEM. A representative histogram of Ab binding to BM-DC is shown on the left graph. ( G ) Binding of SR-A present in lysates of PEM to plate-adsorbed proteins. ( H ) Effects of anti-SR-A 2F8 mAb and AcLDL on the uptake of fluorescently-labelled proteins by BM-DC. Shown are results of single experiments, each representative of at least 3 similar experiments performed (A-D, G, H) or averages +SEM from 4–6 independent experiments (E, F). The data were analysed with the unpaired (A-C, G) or one-sample (H) Student’s t-test or with ANOVA, followed by the Tukey-Kramer post-test (D). *, p < 0.05; ND, not done.
Article Snippet: Moreover, RAGE was expressed on the surface of neither BM-DC nor PEM, as indicated by the absence of specific binding of three different anti-RAGE Ab: rat anti-mouse RAGE mAb (clone 175440, R&D Systems) and two different goat anti-mouse RAGE polyclonal Ab (from R&D Systems and Santa Cruz Biotechnology) ( ).
