The ATO 465 molecule shares the same structure as ATTO 465. It is a fluorescent dye derived from the well - known acridone dye. ATO 465 has moderate hydrophilicity. Its fluorescence can be effectively excited within the range of 420 - 465 nm. This dye has remarkable features such as strong absorption, a high fluorescence quantum yield, excellent thermal stability, and high photostability. In an aqueous solution, this dye exhibits an astonishingly large Stokes shift of 55 nm. When it comes to a solid matrix, especially under low - temperature conditions, the dye emits intense and long - lasting phosphorescence.

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.
