Our comprehensive selection of conjugated antibodies, particularly fluorescent conjugated primary antibodies, are designed to enhance the accuracy and efficiency of your experimental needs. With our expanding collection, researchers can confidently build multiplex panels using high-performance conjugates that deliver reliable and consistent results.
We rigorously validate our conjugated antibodies across key applications, such as flow cytometry, immunocytochemistry, and immunohistochemistry in multi-normal and multi-disease tissue types and samples. By ensuring thorough validation, we provide researchers with confidence in their experimental outcomes, reducing variability and improving data reliability. Our primary conjugates for flow cytometry undergo additional testing in ICC/IF to confirm signal localization, further enhancing their accuracy.
Batch-to-batch consistency is crucial for reproducible results, and our stringent quality control measures and recombinant manufacturing technologies ensure minimal experimental variability. By maintaining a high signal-to-noise ratio, we optimize the specificity and sensitivity of assays, reducing issues like cross-talk. This commitment to quality allows researchers to focus on their studies rather than troubleshooting inconsistencies.
Our pre-validated fluorescent-labeled antibodies eliminate the need for extensive in-house validation, streamlining workflows and allowing for more efficient research. With high specificity and accuracy, these primary conjugated antibodies bind directly to their targets, reducing background noise and minimizing the risk of false-positive results.
If you require customized solutions, we provide tailored antibody conjugation services to meet specific experimental needs. Our expert team will work closely with you to deliver the ideal conjugate for your assays. Available labels for custom conjugation include Alexa Fluor dyes, Phycoerythrin, Allophycocyanin, FITC, Biotin, HRP, Alkaline Phosphatase, Gold nanoparticles, and Oligonucleotide/DNA barcodes.

FAQs
What is an antibody conjugate?
An antibody conjugate is an antibody chemically linked to a specific label, such as a fluorescent dye or enzyme, that enables the detection, visualization, or quantification of a target antigen in various assays.
What is the difference between a conjugated and unconjugated antibody?
A conjugated antibody has a detectable label (a fluorescent dye or enzyme) chemically attached to it, whereas an unconjugated antibody lacks any direct label and typically requires a secondary detection method.
How are conjugated antibodies used in flow cytometry?
In flow cytometry, conjugated antibodies (typically labeled with fluorescent dyes or proteins) bind specific cell surface or intracellular antigens, and when these labeled cells pass through the cytometer’s laser, the fluorophores are excited and emit light that is detected, thereby allowing for the identification and quantification of various cell populations and their protein expression profiles.
What is the role of conjugated antibodies in immunofluorescence microscopy?
In immunofluorescence microscopy, conjugated antibodies specifically bind to target antigens within cells or tissues and, due to their attached fluorescent label, allow visualization of the antigen’s location and distribution when excited by the appropriate wavelength of light.
What are the benefits of using conjugated antibodies?
Conjugated antibodies simplify detection protocols, enhance specificity, and enable multiplexing by directly linking a detectable label, thereby saving time and improving sensitivity in various immunoassays.
