Browse our comprehensive portfolio of conjugated and unconjugated secondary antibodies for fluorescent and chemiluminescent detection of validated* primary antibodies in a wide range of applications, such as cell imaging, flow cytometry and western blotting.
We offer a wide range of specific target and host species antibody conjugates:
Compare classic, Alexa Fluor and Alexa Fluor Plus fluorophore conjugate technologies and get quick links to different secondary antibody conjugates.
Select from 18 different individual Alexa Fluor dyes and 6 different Alexa Fluor Plus dyes. See superior brightness and better photostability.
Discover features and varieties of available horseradish peroxidase (HRP), alkaline phosphatase (AP), biotin, and other enzyme or affinity-tagged secondary antibody conjugates.
New Alexa Fluor Plus 405 conjugated secondary antibodies are now available. Alexa Fluor Plus 405 conjugates are optimized for the highest signal to noise ratio in immunocytochemistry and immunofluorescence applications, with up to 4x the brightness of other 405 conjugates. Continue to expand your multiplexed imaging capabilities by using these bright conjugates to identify low abundance targets, leaving other channels for a different fluorescent imaging readout.
