Primary antibodies are tools used to detect and/or quantify the presence of specific antigens in a range of samples. Our broad portfolio of products includes highly cited monoclonal and polyclonal antibodies, as well as an unrivaled range of recombinant monoclonal antibodies.

Monoclonal and recombinant antibodies

Monoclonal and recombinant antibodies provide high specificity and batch-to-batch consistency, crucial for researchers aiming to obtain reliable, repeatable results in their experiments.

Polyclonal and multiclonal antibodies

These antibodies recognize multiple epitopes on the target antigen, enhancing signal strength and sensitivity, making them ideal for detecting low-abundance proteins. We offer a broad range of highly cited polyclonal antibodies to multiple hosts, including rabbit, mouse, chicken, and goat, for a wide range of applications, such as immunohistochemistry (IHC), immunocytochemistry (ICC/IF), western blotting, ELISA, and flow cytometry.

Conjugated antibodies

Conjugated antibodies are pre-tagged with labels like fluorophores or enzymes, simplifying detection and quantification processes. These are the ideal tools for multiplex IHC and flow cytometry experiments. Our broad range of conjugates includes Alexa Fluor® dyes, FITC, PE, PerCP, APC and tandem dyes.

Carrier-free antibodies

To enhance the flexibility of your experiment, over 10,000 of our antibodies and matched antibody pairs are carrier-free and conjugation-ready, so you can easily find primary antibodies that fit your research needs. Our carrier-free antibodies offer purity and flexibility for further conjugation using our leading Lightning-Link® conjugation kits.

This comprehensive array of antibodies is supported by our commitment to quality, backed by rigorous validation and quality control measures to ensure that each antibody performs optimally in its specified applications.
