Fig. 2From: Culture and detection of primary cilia in endothelial cell modelsSingle staining leads to false positive detection of primary cilia. Arl13b (green) and acetylated \(\alpha\)-tubulin (red) labelling in low (2Â % FBS) serum HMEC-1, showing a lack of staining with arl13b but a false positive cilium labelled with 611b.
