Fluorophore Antibody Conjugation
Labeling antibodies with fluorochromes provides a colored reagent that can be directly observed. The intensity and narrow wavelength of the fluorochromes makes fluorochromes useful tools in immunochemistry. Many of our labels can be used with multiple antibodies that do not cross-react to create custom multiplexed assays.
We are experienced in performing both small-scale and large-scale conjugations and purifications - let us put our expertise to work for you.
We can conjugate antibodies/proteins to many labels, including:
- Alexa Fluor dyes
- Qdot nanocrystals
- ATTO Fluor dyes
- Dylight series
- QCy dyes
- Cascade Blue, Oregon Green, and other Molecular Probes proprietary fluorophores
- Traditional fluorophores - e.g. FITC, TRITC, Texas Red
- Biotins and other haptens
- R-PE, APC and Alexa Fluor tandems
- Horseradish peroxidase, alkaline phosphatase and other enzymes
Don't see the label you are interested in? Just ask. In most cases we can accommodate your request. Consult our experts if you need assistance in choosing the optimal fluorophore for your conjugation.
Cost of Service
For standard antibody conjugations to organic dyes, please contact us for a quote.
To initiate a Custom Antibody Labeling Project:
Contact us to initiate a Custom Antibody Labeling Project. BSI supplies a Polyclonal Antibody Information Sheet with each inquiry to assist in meeting customer specifications.
We will make our best effort to produce the conjugate you request. However, because optimal labeling must be determined empirically, we cannot guarantee that a single conjugation will produce the best product for your needs. Please note that we cannot guarantee the final yield or that the final product will be biologically active. We do not refund payments for services diligently performed.
