AF 568 Acid shares the same chemical structure as Alexa Fluor 568 Acid. It is a bright red fluorescent dye that is optimally suited for use with the 568 - nanometer laser line. The AF 568 dye is soluble in water and is insensitive to pH values ranging from 4 to 10. AF 568 Acid represents the most cost - effective amine - reactive form for conjugating the Alexa Fluor 568 fluorophore with polypeptides.

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.
