Antibody labeling is a critical technique in the biosciences field, enabling researchers to visually track specific antigens in complex biological systems. It hinges on attaching a detectable label to an antibody that binds selectively to its target molecule. This modification allows the labeled antibody to be visualized or detected by special methods, which provides valuable information about the distribution, abundance, and interactions of the target molecule in biological research.

 Tanda offers custom conjugation, labeling, and purification services, providing high-quality conjugates to meet your research or commercial needs. Our range of labels includes oligonucleotides, fluorescent dyes, biotin, enzymes, and more, ensuring applicability for flow cytometry, western blot, IHC, immuno-PCR, PLA, multiplex imaging, and assay development. Whether you choose the antibody from our catalog or provide one to us, our team of experts will tailor a conjugation strategy to meet your specifications.

Fluorescent-Labeling
Direct immunofluorescence with fluorescent-conjugated primary antibodies offers the benefits of reducing background staining, minimizing species cross-reactivity, and simplifying protocols. You can now leverage RayBiotech’s expertise in generating custom fluor-labeled antibodies. We can deliver your labeled antibodies in approximately 2 weeks, with over 17 fluors (e.g. FITC, APC, PE, Cy3, Cy5, Cy7, Fluor 350, Fluor 405, Fluor 488, Fluor 568 and more). 200 µg minimum required; antibodies are provided carrier-free (BSA, KLH, OVA, azide).

Enzyme and Biotin-Labeling
Biotin and enzymes such as horseradish peroxidase (HRP) and alkaline phosphatase (AP) are widely used labels for ELISA, Western blot, IHC, and ELISpot applications. Chromogenic detection of analytes has the advantages of producing a longer-lasting signal, amplifying the detection signal, increasing the stability of the signal, as well as being compatible with light microscopy. Tanda offers a wide range of enzymes for antibody labeling.
