Custom Conjugation & Labeling
Custom Conjugation & Labeling Services
Leverage Enzo's 40+ years of expertise in biochemistry and fluorescent detection to create custom-conjugated antibodies, proteins, and nucleic acids tailored to your research or diagnostic application.
Available Conjugation Chemistries
We label your antibodies and proteins with a wide range of detection molecules
Fluorescent Dyes
FITC, PE, APC, Alexa Fluor® equivalents, Cy3, Cy5, and our proprietary FLUOR DE LYS® dyes. Single or tandem conjugates available for multi-color flow cytometry panels.
Biotin & Enzyme Labels
Biotin (NHS-biotin, biotin-PEG), HRP (horseradish peroxidase), AP (alkaline phosphatase), and streptavidin conjugates for ELISA, Western blot, and IHC applications.
Gold & Specialty Labels
Colloidal gold nanoparticles (5–40 nm), quantum dots, and lanthanide chelates for electron microscopy, lateral flow assays, and time-resolved fluorescence.
Our Custom Conjugation Process
Every custom conjugation project begins with a detailed consultation with our biochemistry team to determine the optimal labeling strategy for your specific application:
- Consultation — Discuss your application, target, and performance requirements
- Chemistry Selection — We recommend the best labeling chemistry and dye-to-protein ratio
- Conjugation — Your antibody or protein is labeled in our ISO-certified facility
- QC & Validation — Each lot undergoes spectrophotometric analysis, SDS-PAGE, and functional testing
- Delivery — Conjugated product shipped with full Certificate of Analysis and stability data
Typical turnaround time is 2–4 weeks depending on the conjugation chemistry and quantity required. Rush services available for urgent projects.
Research Scale
Small-scale custom conjugations for research use, starting from 100 µg of your antibody or protein. Ideal for assay development, pilot studies, and screening experiments.
- Minimum starting material: 100 µg
- Lot sizes from 100 µg to 10 mg
- Research-use-only (RUO) documentation
- Typical turnaround: 2–3 weeks
GMP / Diagnostic Scale
cGMP-compliant custom conjugation for diagnostic kit manufacturing, clinical assay development, and regulated applications. Full validation and documentation packages.
- cGMP manufacturing environment
- Lot sizes from 10 mg to multi-gram scale
- IVD and clinical-grade documentation
- Full traceability and change control
- Stability studies available
