ATTO-TEC’s dyes, antibody labeling kits, labeled phospholipids, and other reagents are used in fluorescence microscopy imaging and can be a key advantage for reliable results, such as in high-plex 3D experiments in cancer research, according to Annette Rinck, president of Leica Microsystems.

The acquisition is expected to provide ATTO-TEC with additional resources to aid in future developments of the product portfolio. “Direct access to knowledge of subsequent imaging and analysis steps leads to new approaches in developing assays, kits, and dyes optimized for the entire workflow,” said Jörg Reichwein, CEO of ATTO-TEC.

According to a press release from Leica Microsystems, ATTO-TEC products will remain available through its existing online store and commercial partners.

Glossary
fluorescence
Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
