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."

DyLight 405

DyLight™ 405 Technical Information

DyLight™ 405 - conjugated secondary antibodies are excited maximally at about 400 nm and fluoresce with a peak at about 421 nm. They are very bright and photostable, but their optimal use requires instruments equipped with a 405 nm laser and a 420 nm emission filter.

The combination of DyLight 405, Alexa Fluor® 488, Rhodamine Red™-X, and Alexa Fluor® 647 provides for maximum color separation, good photostability and high sensitivity.

DyLight 405 is available conjugated to:
