I used a marker for CD206/manose receptor and this is how it looks in the human spleen. What do you think is actually labeling? My guess is the sinusoids…

It should be labeling 206+ macrophages…

Perhaps marginal zone macrophages surrounding white pulp and the background dark areas are the red pulp?
