Sorry for not relaying the specific information on this issue.
I am referring to Alexa Fluor 568 Dye purchased from Molecular Probes
Hope it helps

Which Alexa dye are you using? Where did you purchase it from. I was just
interested if it came from Molecular Probes.
Thanks for the information
Alexa RED does not exist, if you refer to Molecular probes productes.
