ATO 532 Acid has an identical molecular structure to ATTO 532 Acid. It is a fluorescent label related to the well - known dye Rhodamine 6G. This dye is characterized by strong absorption, a high fluorescence quantum yield, excellent thermal and photostability, and good water solubility. Thanks to these features, ATO 532 is highly appropriate for single - molecule detection applications and high - resolution microscopy techniques, including Photoactivated Localization Microscopy (PALM), direct Stochastic Optical Reconstruction Microscopy (dSTORM), Structured Illumination Microscopy (SIM), and Stimulated Emission Depletion Microscopy (STED). In addition, it is also very suitable for use in Fluorescence - Activated Cell Sorting (FACS) and Fluorescence In Situ Hybridization (FISH). The fluorescence of ATO 532 Acid can be most efficiently excited within the range of 515 - 545 nanometers.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
