Primary antibodies are large, Y-shaped glycoproteins (also known as immunoglobins) generated by the immune system in response to foreign agents. They recognize antigens specifically, with high affinity, and are therefore widely used in scientific research to localize, purify and quantify proteins. They may also be used as therapeutic agents to deliver drugs to specific cell populations.

Our broad portfolio includes highly cited monoclonal and polyclonal antibodies, plus our unrivaled range of recombinant antibodies. You can find primary antibodies that fit your research’s needs with conjugated antibodies and carrier-free formulations.

Abcam’s research area experts are always searching for the most novel targets, and scalable long-term supply in our recombinant monoclonal antibodies means you can always access the antibody you need.

We are committed to addressing the reproducibility crisis in research, so knock-out (KO) validation is always part of our processes where possible. We extensively validate our antibodies across applications including flow cytometry, western blot, immunohistochemistry (IHC), and immunocytochemistry (ICC/IF). We review our validation data 80,000 times per year.

Features

​​Recombinant rabbit monoclonals

Recombinant manufacture overcomes traditional limitations to give you improved sensitivity and confirmed specificity. 

Carrier-free antibodies

Recombinant monoclonals and matched pairs available in BSA and azide-free formulations give you a flexible, simple research solution.

Conjugated primary antibodies

Choose from over 3,000 fluorescent-labeled antibodies, extensively validated in IF and flow cytometry, to develop your multiplex panel.

Webinar: how can knock-out validation support the reproducibility of your experiments?

Join Dr. Alejandra Solache, VP of New Product Development, as she discusses the value of gene knock-out (KO) technologies in large-scale antibody screening.
