Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation. Atto 550, which is similar to Cy3, may be useful in applications such as fluorescence resonance energy transfer (FRET) and as a tag for molecules such as secondary antibodies. Atto 550-Biotin is suitable for fluorescence labeling of avidin/streptavidin conjugated molecules.

Immunocytochemical investigations of fixed cells are used to enhance diagnostic accuracy in haematology and oncology. The alkaline-phosphatase/anti(alkaline phosphatase) technique, immunoperoxidase and the avidin-biotin technique are the most important methods in immunocytochemistry. Tyramide-enhanced immunostaining is a new powerful technique. Peripheral blood...
