Images of FISH in suspension (FISH-IS) using the isolated nuclei and chromosomes of <i>Karenia mikimotoi</i>.

DAPI-stained DNA (blue) and in situ hybridization of the Dy547-labeled oligonucleotide (CCCTAAA)3 used to localized telomeric repeats (red) (A, B´, C´ and E) and the FITC-labeled oligonucleotide (CT)10 used to paint the AG-chromosome (green) (A, B, C and D) in interphasic nuclei (A), isolated chromosomes (B, C) and mitotic nuclei with different degrees of chromosomal condensation (D, E). Arrowheads in B and C point to interstitial clusters of CT repeats. The arrow in C points to the strongly labeled AG-chromosome. Scale bar = 10 μm.
