Expert Antibody Conjugation Service for Your Research

Boster's custom antibody conjugation services combine decades of antibody expertise with a comprehensive selection of labels for flow cytometry, immunofluorescence, Western blot, and select in vivo imaging workflows. Our antibody conjugation service supports both research-grade and preclinical workflows. Whether you need standard HRP and biotin conjugation or advanced fluorescent dyes like Alexa Fluor, PE, or APC, our optimized conjugation protocols deliver stable, low-background conjugates that perform reliably in your assays.

Our antibody labeling service supports a wide range of applications including antibody-oligonucleotide conjugates, protein conjugation for imaging and detection that can complement any preferred protein conjugation kit, and custom conjugation chemistry matched to your downstream workflow. We work with your existing antibodies or can source and conjugate antibodies on your behalf, simplifying vendor management and accelerating your project timeline. Availability depends on antibody format, scale, and chemistry feasibility; projects are quoted case-by-case.

Start your worry-free antibody labeling experience by submitting the form above. Our antibody specialists will respond within 24 hours with a detailed quote and timeline tailored to your project.

Conjugation Tiers to Fit Your Budget and Timeline

We offer flexible antibody conjugation options so you can choose the right balance of speed, scale, and customization. Whether you need rapid conjugation for a pilot study or fully optimized custom conjugates for clinical or in vivo work, our team will help you scope the solution that fits your application and budget.

• Standard Conjugation: Fast turnaround for common labels (HRP, biotin, FITC, Alexa Fluor) with proven protocols—ideal for flow cytometry panels and routine immunofluorescence.
• Optimized Conjugation: Extended optimization for challenging antibodies or specialized applications requiring minimal background and maximum stability.
• Custom Conjugation: Tailored chemistry for antibody-oligonucleotide conjugates, in vivo imaging labels, or novel fluorophore conjugation—backed by full method development and validation.

Turnaround for standard projects is typically ~2 weeks; optimized and custom projects vary based on development scope.

Not sure which tier is right for you? Our antibody specialists will consult with you to recommend the best approach based on your assay requirements and sample constraints.

We support a comprehensive menu of conjugate labels for antibody conjugation, including enzymes, biotinylation reagents, and a wide range of fluorescent dyes optimized for flow cytometry, immunofluorescence, and in vivo imaging, whether you prefer a full service workflow or an antibody fluorophore conjugation kit approach. Excitation and emission wavelengths are provided for fluorescent labels to help you design multicolor panels and avoid spectral overlap. Violet-excited dyes (e.g., BV series) are available upon request, and we can advise on selecting a BV421 conjugation kit if you plan parallel in-house work.

Wavelength values are representative; exact excitation/emission characteristics may vary slightly by dye lot and instrument configuration.

Antibody Input Requirements and Scale Planning

To ensure successful conjugation and optimal yields, antibodies should meet the following input specifications:

• Format: Purified IgG (polyclonal or monoclonal) in liquid or lyophilized form
• Concentration: Minimum 1.0 mg/mL for liquid samples (higher concentrations preferred for small-scale projects)
• Purity: Preferably free of carrier proteins (e.g., BSA), sodium azide, and primary amine–containing buffers (e.g., Tris, glycine). If present, buffer exchange can be performed as part of the service.
• Minimum amount: 1 mg typical minimum; smaller quantities may be feasible depending on conjugate and workflow
• Shipping: Ship on wet ice or dry ice to maintain antibody stability

Our team will provide expected yields based on your input amount and conjugation chemistry, so you can plan downstream experiments with confidence. If your antibody requires buffer exchange or additional purification, we can handle that as part of the service.
