Antibody conjugation kits

The fast way to label your primary antibody

Our antibody conjugation kits allow you to rapidly add the label of your choice onto your primary antibody. Choose from labels that include enzymes, biotin/streptavidin, fluorochromes and gold for use in a wide range of immunodetection protocols (Flow cytometry, western blot, ELISA, IHC and more...).

The antibody conjugation procedure:

Our antibody conjugation kits allow a quick and easy process with less than one minute hands-on time to label an antibody of your choice, for whatever application you need. The kits offer you the advantage of being a one-step labeling method with no separation steps.

In contrast to traditional labeling methods, current data shows the antibody conjugation process does not affect the epitope recognition and immunoreactivity of your primary antibody.

Conjugation Process

Tips for sucessful conjugation:

The purity and concentration of your antibody are important for successful conjugation. As the antibody labeling chemistry involves free amine groups, any protein present in the mixture will become conjugated during the conjugation process - the antibody to be conjugated should be in 10-50mM amine-free buffer within a pH range of 6.5-8.5, modest concentrations of Tris buffer (up to 20mM) are also tolerated. In addition the amount and concentration of the antibody to be labled should be more than or equal to 10µg.

For optimal conjugation you may need to purify or concentrate your antibody using our purification and concentration kits.

What other researchers say:

"Using the Biotin conjugation kit was very easy and quick. We achieved excellent results in an antibody labeling reaction. The epitope-recognition of the antibody was not affected and detection via streptavidin-HRP is very sensitive"

Researcher, University of Giessen - Germany

"The R-Phycoerythrin conjugation kit was extremely easy to use and effective despite the very small amount of antibody labeled (60µg). Minimal handling and it worked!!"

Researcher, University of California - USA
