Service Overview
Rabbit monoclonal antibodies are monoclonal antibodies derived from rabbit B cells, offering high affinity and epitope diversity that complement traditional mouse monoclonal platforms. This service serves academic laboratories, biotechnology companies, diagnostic developers, and pharmaceutical research teams requiring high-affinity recognition, superior immunohistochemistry performance, and strong immune responses to conserved or low-immunogenicity targets.
We provide comprehensive services from antigen preparation, immunization, screening, recombinant expression, to antibody purification and quality control, utilizing integrated rabbit monoclonal antibody development platforms.
Workflow Overview
Rabbit monoclonal antibody development follows a structured multi-stage workflow from antigen design to final QC.
Each stage is optimized to ensure high-affinity clone selection and consistent antibody quality.
Supported Antigen Types
- Recombinant proteins
- Synthetic peptides (linear or cyclic)
- Membrane proteins and GPCRs
- Cytokines and chemokines
- Viral antigens (native or recombinant)
- Bacterial proteins and toxins
- Phosphopeptides (site-specific)
- Receptor extracellular domains (Fc fusion or His-tagged)
- Low-immunogenicity and highly conserved targets
Immunization and Screening Platforms
Immunization Protocol Selection
| Antigen Type | Recommended Immunization Strategy |
|---|---|
| Soluble high-purity protein | Conventional adjuvant immunization, titer monitoring at 4–6 weeks |
| Hydrophobic/membrane protein | Recombinant extracellular domain, LNP reconstitution, or cell-overexpression immunization |
| Short peptide (<15 aa) | KLH/BSA conjugation immunization |
| Phospho-epitope | Parallel immunization with phospho- and non-phospho peptides + subtractive screening |
| Conserved/low-immunogenicity protein | Rabbit immune system typically shows better response; multiple strategies available |
Rabbit Monoclonal Development Platforms
We utilize integrated rabbit monoclonal antibody platforms, including both hybridoma-based and B cell-based workflows, selected based on project requirements:
- Hybridoma platform: Cell fusion, hybridoma generation, clonal selection, and stabilization
- Single B-cell platform: Antigen-specific B-cell isolation, single-cell screening, and direct antibody sequence recovery
Both platforms support high-affinity rabbit monoclonal antibody generation with flexible downstream applications.
Screening Strategy and Functional Validation
Screening protocols are customized based on final application requirements, not fixed templates.
Common Screening Methods
ELISA: Binding activity, cross-reactivity, pairing capability
Western blot: Specificity confirmation under denatured and reducing conditions
Flow cytometry: Native conformation recognition of cell surface antigens
IHC/IF: Localization capability in tissues or cells (rabbit antibodies often excel in these applications)
Neutralization/blocking assays: Functional activity screening (receptor-ligand systems)
Screening Phase Description
| Phase | Description | Duration |
|---|---|---|
| Primary screening | Binding activity assessment of supernatants or isolated B cells | 3–7 days |
| Secondary screening | Functional or cross-reactivity validation of positive candidates | 1–2 weeks |
| Stabilization screening | Confirmation of antibody performance consistency | 1–2 weeks |
Antibody Production and Quality Characterization
Standard Quality Control Items
| Parameter | Method | Acceptance Criteria (Example) |
|---|---|---|
| Purity | SDS-PAGE (reducing/non-reducing) | >90% |
| Concentration | A280 or BCA | Reported actual value |
| Endotoxin | LAL method | <1 EU/mg (can be reduced to <0.1) |
| Isotype | Antibody isotyping kit | Rabbit IgG, IgA, IgM |
| Functional validation | ELISA/flow cytometry/IHC/WB, etc. | Consistent with project goals |
Additional characterization such as affinity (SPR/BLI), thermal stability (DSF), aggregation (SEC) can be added upon request.
Technical Principles and Applications
Technical Characteristics of Rabbit Monoclonal Antibodies
| Feature | Technical Implication |
|---|---|
| High affinity | Typically 10–100x higher than mouse monoclonal antibodies |
| Epitope diversity | Recognizes unique epitopes that may not elicit response in mice |
| Superior IHC/IF performance | Rabbit antibodies often perform better in tissue staining |
| Strong response to conserved targets | Rabbit immune system recognizes small peptides and conserved proteins effectively |
| Recombinant platform compatibility | Easily transition to recombinant expression for long-term reproducibility |
Typical Applications
Rabbit Monoclonal vs. Mouse Monoclonal: A Comparison
| Feature | Rabbit Monoclonal | Mouse Monoclonal |
|---|---|---|
| Affinity | Typically higher (10–100x) | Moderate |
| Epitope recognition | Broader, unique epitopes | More limited |
| Response to conserved targets | Generally stronger | Often weak or absent |
| IHC/IF performance | Excellent | Variable |
| Small peptide recognition | Recognizes smaller peptides | Requires longer peptides |
| Hybridoma stability | Stable but less common | Highly stable, widely used |
| Recombinant production | Fully supported | Fully supported |
| Diagnostic validation | Emerging | Extensive, gold standard |
Frequently Asked Questions
Q: When should I choose rabbit monoclonal over mouse monoclonal?
Rabbit monoclonal antibodies are recommended for conserved or low-immunogenicity targets, IHC/IF applications, or when high affinity is critical. Mouse monoclonal remains a strong choice for diagnostic assays with established validation workflows.
Q: Can rabbit monoclonal antibodies be used in diagnostic assays?
Yes. Rabbit monoclonal antibodies are increasingly used in diagnostic development. We recommend evaluating on a per-project basis.
Q: Do you offer both hybridoma and single B-cell platforms?
Yes. We select the appropriate platform based on your antigen, application, and downstream requirements.
Q: Can you guarantee that the final antibody will work in IHC or flow cytometry?
We use conditions aligned with final applications whenever possible during screening. However, cross-target guarantees cannot be made. Screening protocols and acceptance criteria can be established at the initial project phase.
Q: Can I use only part of the service (e.g., immunization and screening only)?
Yes. Service scope can be segmented according to project needs, with module-based pricing.
