"I have used a wide variety of secondaries and Jackson ImmunoResearch has consistently been the best. The fluorophores are bright and stable and their selective (x reactivity removed) secondaries have always shown species specificity in multiple labeling."

Alexa Fluor® 680 and 790

Alexa Fluor® 680 and 790 Technical Information

Alexa Fluor® 680 and Alexa Fluor® 790 conjugates are used for very sensitive Western blots, ELISAs, and multiplexing arrays. Alexa Fluor® 680 conjugates are excited with a peak around 684 nm and fluoresce with a peak around 702 nm. Alexa Fluor® 790 conjugates are excited with a peak around 792 nm and fluoresce at a peak around 803 nm. They are the best choice for highly sensitive single or double labeling with fluorescence imaged in a LI-COR Odyssey® imager.
