Antibody conjugation/labeling service
Cell Signaling Technology
CST has more than 1500 ready-to-ship antibody conjugates for flow cytometry, immunofluorescence, high-content screening, and other immunoassays.
Direct conjugation experts can build specific antibody-label combinations so you can sidestep the time sink and pitfalls that come with do-it-yourself kits.
Choose from a broad conjugation offering including beads, fluorescent dyes, HRP, biotin/haptens, oligonucleotides and more.
Validated
Conjugated antibodies are analyzed using size exclusion chromatography to verify their physical integrity and ensure preparations are free of contaminants, such as antibody aggregates or fragments, that may interfere with your experiments. Testing in key applications using biologically relevant cell systems and controls is also available.
Optimized
Stringent purification to remove free dye/label and antibody, optimization of bio-conjugation chemistries, and identification of optimal degree of labeling ensures the best signal-to-noise ratio and the highest-quality product.
Order guarantee
Antibody loss occurs during every conjugation and cleanup process. We account for varying labeling efficiencies, absorb the cost of any excess antibody required to manufacture your conjugate, and ensure you receive exactly the amount of antibody you requested.
Flexible
Multiple tiered options are available to match your needs and budget — from basic antibody conjugation to full validation and stability testing.
Support
Extensive technical support and consultation are provided by the same scientists who produce and validate our commercially available antibodies.
Basic conjugations typically ship within 10 days, complex conjugations may take 3-4 weeks.
