In order to address your feedback fully, we felt it necessary to split Figure 7. The data contained in the original Figure 7 is now split between Figure 7 (deals with CD14 and CD68 only) and Figure 8 (deals with CD11b and CD36).
The red population shows positive binding of anti-CD36 and anti-CD11b to the U937 cells (gated on the previous plot S4A, FSC/SSC).
