Detection of Crenarchaeota by fluorescence microscopy and gene probes (CARD-FISH)

CARD-FISH is a sensitive method for the specific staining of cells of certain prokaryotic groups. On the left-hand side are shown all unspecifically DAPI-stained cells from a pelagic redoxcline of the Baltic Sea; on the right side is the same sample with those cells that hybridized with the Crenarchaeota-specific probe Cren679 (Labrenz et al. 2010).
(CARD-FISH = catalyzed reporter deposition fluorescence in situ hybridization)
