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.
  • Our primary conjugates for flow cytometry are also validated through ICC/IF testing to confirm the signal localization.
  • Thorough validation means you can have greater confidence in the reliability of your results from the very start of your experiments. 

Consistent batches:

  • We perform stringent quality checks to bring consistency to our products for more accurate results in the lab.
  • 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.

 Less in-house work:

  • Our validated fluorescent-labeled antibodies eliminate the need for long hours of in-house validation facilitating efficiency in your research process. 
  • This allows you to focus more on advancing your research and achieving your goals.

High-sensitivity solutions:

  • Our primary conjugated antibodies directly bind to the target bringing specificity and accuracy to your results.
  • By eliminating the need for the secondary antibody, our conjugate antibodies help reduce the chances of false positive results providing reliable outcomes. 

Diverse fluorophore range:

  • We have an extensive selection of fluorophores to help you stay at the forefront of conjugated flow cytometry innovation.
  • With the likes of Alexa Fluor® Dyes, FITC, PE, PerCP, APC, and tandem dyes, you can achieve high-resolution results with maximum sensitivity.
