End-to-End Antibody Development, From Antigen to Application

ICDMO's antibody development platform integrates immunology expertise, advanced hybridoma technology, phage display, and recombinant expression to deliver custom antibodies of exceptional quality. Whether your goal is a research-grade polyclonal serum, a hybridoma-derived monoclonal for diagnostic standardization, or a sequence-defined recombinant IgG for therapeutic development, our team manages every step from antigen design through application validation.

Every antibody project is supported by rigorous titer monitoring, specificity confirmation, and application-specific validation. We offer optional epitope mapping, affinity measurement (SPR/BLI), isotype determination, and conjugation services to deliver a fully characterized antibody ready for your intended use.

Three Core Antibody Platforms

Each platform is supported by dedicated scientists with deep immunology and protein engineering expertise.

Polyclonal Antibodies
Polyclonal Antibodies

High-sensitivity polyclonal antibodies generated in rabbit, mouse, goat, sheep, guinea pig, or chicken. Ideal for Western blot, ELISA, and IHC applications.

Multiple hosts4–8 weeksHigh sensitivity
Monoclonal Antibodies
Monoclonal Antibodies

Murine or rabbit hybridoma-derived monoclonal antibodies with defined epitope specificity. High batch-to-batch consistency for standardized assay development.

Defined epitope3–4 monthsHybridoma platform
Recombinant Antibodies
Recombinant Antibodies

Sequence-defined recombinant IgG, Fab, scFv, and nanobody formats expressed in CHO or HEK293. Ideal for therapeutic development and standardized diagnostics.

Sequence-definedGMP-compatibleAny format

What We Offer

Immunization & Antigen Preparation

Recombinant protein, peptide conjugate (KLH/BSA), DNA, cell, and VLP antigens accepted
Custom antigen design and production service available if required
Multi-species immunization: rabbit, mouse, rat, goat, sheep, guinea pig, chicken

Development Workflow

1
Project Consultation & Antigen Review
Submit your antigen information (sequence, structure, target epitope, intended application). Our scientists assess immunogenicity and recommend immunization strategy and host species.
2
Antigen Preparation
Recombinant protein expression or peptide synthesis. Peptides coupled to KLH/BSA carrier. QC by SDS-PAGE and endotoxin testing before immunization.
3
Animal Immunization & Titer Monitoring
Immunization in selected host species. Serum collected at defined intervals and titer verified by ELISA. Booster injections until target titer achieved (typically ≥1:10,000).
4
Hybridoma Fusion & Primary Screening (mAb only)
Spleen cell fusion, HAT selection, and ELISA primary screening of ~1,000 clones. Positive wells identified within 2–3 weeks of fusion.
5
Secondary Screening & Subcloning
Specificity confirmation by Western blot, IF, or FC. Two rounds of limiting dilution subcloning to ensure monoclonality. Isotype determination by lateral flow assay.
6
Antibody Production, Purification & QC
Scale-up in bioreactor or ascites. Protein A/G purification to >95% purity. Final QC: SDS-PAGE, Western blot, ELISA titer, endotoxin. CoA and sequence report delivered.
