FACS analysis of cell surface TLR4 in human monocyte-derived dendritic cells using NB100-55951 at 1:200 (2.5 ug). FACS analysis of cell surface TLR4 in human monocyte-derived dendritic cells using NB100-55951 at 1:200 (2.5 ug). Black and green open histograms represent unstained cells and negative control (anti-human CD14 FITC), respectively. Blue open histogram is NB100-55951 anti-TLR4 stained Dendritic cells.
