"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."Janet Duerr, Ohio University

Alexa Fluor® fluorescent dyes are widely recognized as superior fluorescent dyes, respected for their brightness and photostability. They are suitable for a variety of applications including confocal microscopy, flow cytometry, fluorescent Western blotting, and fluorescent ELISA. Alexa Fluor conjugated secondary antibodies can be used exclusively or in combination with other fluorescent probes to generate an optimal multiplex dye panel for your experimental variables.
JIR provides Alexa Fluor 488, 594, 647, 680, 790 conjugates.
Antibodies conjugated with far-red- and Infrared-emitting dyes are more sensitive than those with dyes emitting visible light due to low fluorescence quenching of the conjugates, high extinction coefficients of the dyes, and low background autofluorescence. The increased brightness allows for a wider range of immunofluorescence detection and imaging modalities. Far-red and Infrared dye conjugates can be used for higher sensitivity Western blots, quantitative Western blots, in-gel Western blots, microWestern arrays, in-cell Western arrays, on-cell Western arrays, tissue section imaging, small animal whole body imaging, and other techniques that require the brightest dyes.
Western blot using Alexa Fluor® 680 far-red dye and Alexa Fluor® 790 infrared dye. Alexa Fluor® 790-goat anti-mouse IgG, Fcγ Subclass 1 specific (min X Hu, Bov, Rb Sr Prot, 115-655-205)(green) shows heavy chains and Alexa Fluor® 680-goat anti-mouse IgG, light chain specific (min X Bov, Gt, Hrs, Hu, Rb, Rat, Shp Ig, 115-625-174)(red) shows light chains.
