Fc site-specific labeling provides stricter control by targeting the Fc region of antibodies, thereby achieving well-defined immune conjugates. This method ensures that antibody labeling occurs specifically at the Fc site, thereby enhancing the uniformity and functionality of antibody binding complexes. Usually, this method allows each antibody to add 2-4 labels, striking a balance between effective labeling and maintaining antibody biological activity. By focusing on the Fc region, this technique minimizes the risk of interfering with antigen binding sites, thereby maintaining the specificity and effectiveness of antibodies. This labeling method has the following advantages:

• improveUniformity of conjugated groups, improving reproducibility and efficacy

• Preservation of antigen binding

• By reducing the risk of inducing immune responses to bound antibodies,Reduce immunogenicity

• Promote multifunctionalityAttach multiple molecules or payloads to a designated location

• By avoiding purification stepssimplifymanufacture

Flow cytometry analysis:

Flow cytometry data shows a correlation with SureLight ®R-Phycoerythrin（PE）And SureLight ® Isomeric cyanideAllophycocyanin (APC).Taking the example of antibodies. A431 cells expressing EGFR in humans were stained with Cetuximab (humanized anti EGFR monoclonal antibody), which binds to R-PE or APC. Stained cells were analyzed on a BD FACS CANTO II flow cytometer. The fluorescence intensity of cells stained with Cetuximab conjugate is displayed as a shaded histogram. Compare the open histogram of isotype stained cells.
