Antibody labeling kits

Antibody conjugation, also known as antibody labeling, is the process of chemically linking an antibody to a specific tag. When conjugated a primary antibody directly detects the target antigen of interest, without the need for a secondary antibody. Labels can include fluorescent dyes, enzymes or proteins and your choice or combination of labels will depend on the experimental application, as well as your multiplex panel. Conjugation or labeling kits provide all the tools you need to label a primary antibody, without the need to learn complex chemistry and separation techniques.

Our Lightning-Link® conjugation kits are easy to use and allow you to conjugate antibodies in three simple steps to more than 45 labels including fluorescent proteins (Alexa Fluor® and DyLight Fluor® dyes), tandem dyes, enzymes, oligonucleotides, and gold nanoparticles.

To generate high-quality conjugates choose from our range of carrier-free antibodies and antibody pairs specifically designed for antibody labeling. We offer 10,000 formulations free from glycerol, BSA and sodium azide to reduce antibody loss and maximise conjugation efficiency. 

If your antibody does not meet these buffer requirements, you can easily purify or concentrate using our range of purification and concentration kits. Our experts can also work with you to develop customized conjugation kits that fit your needs, so you can scale up with confidence.
