"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."

The dilution factors suggested in the following table are presented as ranges because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The optimal working dilution should be determined empirically for each application.
