Fluorophore Custom Conjugation

Sometimes what you need isn’t in the catalog. Our custom services – including antibody and toxin conjugation, bulk ordering, and lot reservation –deliver the exact format, label, and quantity you need, without changing suppliers or validation standards.

Fluorophore Custom Conjugation

Primary fluorophore-conjugated antibodies allow direct fluorescent immunodetection methods without the need for a secondary antibody. Direct immunodetection renders your experiment quicker and cheaper while simultaneously reducing non-specific binding of the secondary antibody and producing higher quality data.

Customizable

Custom antibody and toxin conjugation to fluorophores, enzymes, or biotin, tailored to your specific assay and experimental design.

Conjugation Ready

Well-characterized antibodies and toxins optimized for conjugation while preserving binding specificity, biological activity, and detection performance.

Broadly Compatibility

Suitable for immunofluorescence, flow cytometry, immunoassays, and multiplex detection workflows using directly labeled reagents.

Consistent  Quality

Controlled production, bulk ordering, and lot reservation options ensure long-term consistency and reproducibility across experiments.

Uses & Applications

Our custom conjugation services support antibody- and toxin-based detection across a wide range of research applications, enabling direct, sensitive, and reproducible results. These conjugated reagents are optimized for direct detection and multiplex assay design.

Immunofluorescence (IF, ICC, IHC)

Conjugated reagents enable low-background immunofluorescence and immunohistochemistry without secondary antibodies.

Western Blot & Blot-Based Assays

Fluorophore-conjugated primary antibodies enable direct, consistent detection in fluorescent western blot and blot-based assays.

ELISA

Fluorophore-conjugated antibodies support sensitive and reproducible ELISA-based detection.

Multiplex Immunodetection

Simultaneous multi-target detection using spectrally distinct fluorophore conjugation for multiplex assays.

Flow Cytometry & Imaging Flow Cytometry

Custom-labeled antibodies support flow cytometry panel design and robust multiplex analysis of surface and intracellular markers.

In Vivo

Custom conjugation allows tailored labeling for selected in vivo studies, improving consistency and signal quality.

Tissue Clearing

Optimized labeling strategies for tissue clearing, improving signal penetration and image clarity.

Pull-Down & Capture Assays

Biotin-conjugated antibodies and toxins support streptavidin-based pull-down and protein interaction studies.

Available Fluorophore Options

We offer fluorophore-custom antibody conjugation services for direct detection in immunofluorescence, flow cytometry, and related assays. Directly conjugated reagents simplify workflows, reduce variability from secondary antibodies, and enable robust multiplex detection.
