Rabbit Monoclonal Antibodies

The Rabbit-mAb™ 3.0 generation of Recombinant Rabbit Monoclonal Antibody Service is exclusively available from ABclonal. Rabbit-mAb™ employs innovative cell sorting, enriching, bioinformatics, and recombinant monoclonal antibody technologies. ABclonal selects the desired monoclonal antibody directly from B cells.

Our rabbit monoclonal technologies provide more candidates that are unreachable by traditional technologies – our in-house bioinformatics optimize the selection, our new generation of gene synthesis solutions cut down the cost of antibody engineering, and our XPromoter 2.0 can highly express recombinant antibodies.

ABclonal provides custom rabbit monoclonal antibodies with high-specificity and high-sensitivity in multiple applications and manufactures cost-efficient, large-scale antibodies.

Phase I: Immunization

Phase II: Cell Sorting, Screening, Sequencing

Phase III: Cloning, Expression, and Characterization

To work with us, please provide:
  1. The antigen information: ABclonal will produce the immunogens for you, such as peptides, recombinant proteins, etc.
  2. Prepared immunogens: such as peptides, proteins, small molecules, or other samples.
  3. Spleen and blood of an immunized rabbit: ABclonal will initiate the custom monoclonal antibody development.

We also provide comprehensive services for antibody cloning, engineering, expression, and purification in addition to custom antibody development.

The Advantages And Applications Of Rabbit mAb

10-10 - 10-12 M, 10-100 times higher KD than mouse mAbs

Superior specificity

GALT and B cell maturation

Broad epitope recognition

Less immunodominance, more diversity

Good hapten recognition

Express groups 1-3 CD1 proteins

Great Stability

Extra disulfide bonds

One major IgG isotype


High-affinity antibody

Modification-state antibody

Anti-idiotype antibody

Antibody pairing and ELISA kit

Research and in vitro diagnostics

Able to differentiate between subtle structural variations

Fit for low-abundance biomarker quantification
