Whole IgG Affinity-Purified Secondary Antibodies

"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 Technical Information

Alexa Fluor® 680 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. They can be visualized with a LI-COR Odyssey® imager and other fluorescence detection systems, and they can be used for double labeling with Alexa Fluor® 790 conjugates.
