ATO 488 has the same molecular structure as ATTO 488. It is a new type of hydrophilic fluorescent dye that offers excellent water - solubility, strong absorption capacity, a high fluorescence quantum yield, as well as outstanding thermal and photostability. Due to these remarkable properties, ATO 488 is highly suitable for single - molecule detection applications and high - resolution microscopy techniques such as Structured Illumination Microscopy (SIM) and Stimulated Emission Depletion Microscopy (STED). Moreover, this dye is also well - suited for use in Fluorescence - Activated Cell Sorting (FACS) and Fluorescence In Situ Hybridization (FISH).

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.
