Custom fluorescent antibody conjugation for immunofluorescence, flow cytometry, confocal imaging, multiplex assay development, and other fluorescence-based analytical workflows. Support includes labeling with FITC, Alexa Fluor dyes, Cy dyes, and near-infrared fluorophores, with workflow design aligned to antibody type, application, and signal requirements.
Antibody fluorescent labeling enables sensitive detection and visualization of biological targets by covalently attaching fluorophores to antibodies. This approach is widely used to support cellular imaging, protein localization studies, flow cytometry, and multiplex analytical workflows where strong signal and spectral flexibility are important.
Bio-Synthesis provides custom fluorescent antibody labeling using a broad range of dye options selected for compatibility with your target application. The labeling strategy, fluorophore class, and degree of labeling are aligned to preserve antibody activity while delivering signal intensity appropriate for fluorescence microscopy, immunofluorescence, confocal imaging, flow cytometry, and other detection workflows.
