Zip Alexa Fluor Rapid Antibody Labeling kits allow you to efficiently label your precious antibody with Alexa Flour dyes to create an antibody conjugate that is ready to use within 15 minutes.
• Very fast and easy to use • 100% antibody recovery—no purification steps • Useful for a wide range of applications • No chemistry or conjugation experience needed • With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters
The kit contains everything you need to perform three separate labeling reactions. Conjugates are ideal for multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and indirect FISH.
Better results and workflows with labeled primary antibodies A primary antibody directly labeled with a fluorophore often produces lower background fluorescence and less nonspecific binding. Further, multiple primary antibodies of the same isotype or derived from the same species can easily be used in the same experiment if they are directly labeled with compatible fluorophores.

Superior Alexa Fluor dyes Compared to traditional dyes, Alexa Fluor dyes are brighter, more photostable, and more pH resistant between pH 4 and 10. And generally when using Alexa Fluor dyes, higher degrees of labeling can be achieved without intramolecular quenching. For details see Alexa Fluor Dyes Spanning the Visible and Infrared Spectrum—Section 1.3.
