Figure 4. Positive and negative control tissue.

Figure 4

Tonsil tissue was used as a positive control for CD100 (panel a), CD45 (panel b), CD72 (panel c) and CD68 (panel d). A positive reaction for CD100 (panel a, see inset), CD45 (panel b, see inset) and CD72 (panel c, see inset) was detected in lymphocytes, and a positive reaction for CD68 was seen in macrophages (panel d, see inset). Negative control is shown in panel e. a,b,c,d,e: Bar = 30 µm; insets: Bar = 300 µm.
