"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® 594 - conjugated antibodies absorb light maximally around 591 nm and fluoresce with a peak around 614 nm. They are brighter, more photostable and more hydrophilic than Texas Red conjugates. Alexa Fluor® 594 conjugates are brighter than other red-fluorescing conjugates, and they provide better color separation from green-fluorescing dyes than Cy™3 and TRITC conjugates. They are the best choice for immunofluorescence detection in the deep-red region of the visible spectrum.
