Why choose Abcam's conjugated antibodies?

- Highly validated: Whenever possible, we validate our primary conjugates in functional applications, including flow cytometry, ICC/IF, and IHC/IF and western blot.

- Consistent batches: Our quality assurance process is designed to reduce variability and ensure a high signal-to-noise ratio during your experiments involving the engineering of recombinant fluorescent antibody conjugates or removing free dye.

- Time saving: Our validated conjugated antibodies mean you don’t need to directly conjugate and validate your antibodies, so you can focus on advancing your research and achieving your goals.

- Quicker assay: Our conjugated primary antibodies eliminate the need for a secondary antibody, streamlining your protocol and reducing assay time.

- Reduced background noise: By removing the need for the secondary antibody, our conjugated antibodies help reduce the chances of false positive results.

- Custom antibody conjugation: We offer custom conjugation services to meet your unique antibody labeling needs. Our team of experts works closely with you to deliver the best conjugate for your assay.

We offer a wide range of labels, including:

• Alexa Fluor^® dyes: 405, 488, 532, 555, 568, 594, 647, 680, 600, 750, 790
• Phycoerythrin (PE), allophycocyanin (APC), luorescein isothiocyanate (FITC)
• Biotin, horseradish peroxidase (HRP), alkaline phosphatase (AP)
• Gold nanoparticles (10, 20, 40 or 80 nm)
• Oligonucleotide/DNA barcodes

Conjugated antibodies allow for direct detection of target antigens in various assay formats. By coupling antibodies with a detection molecule, you can readily visualize the presence and quantity of specific proteins without secondary antibodies. These conjugates are essential in applications ranging from western blotting and immunohistochemistry to enzyme-linked immunosorbent assays (ELISA) and flow cytometry.

Types of conjugated antibodies

HRP conjugated antibodies

These antibodies are conjugated to HRP and are typically used for enhanced chemiluminescent detection in immunoblotting and other immunoassays.

Alexa Fluor® conjugated antibodies

Conjugated with highly fluorescent Alexa Fluor^® dyes, these antibodies provide superior brightness and photostability for fluorescence microscopy and flow cytometry.

PE conjugated antibodies

Linked to PE, these antibodies offer intense fluorescent labeling for flow cytometry applications, enabling precise cellular analysis.

Other conjugated antibodies

In addition to HRP, PE, and Alexa Fluor® conjugates, a variety of other conjugated antibodies exist, including popular labels such as fluorescein isothiocyanate (FITC), allophycocyanin (APC), alkaline phosphatase (AP), and biotin.
