ZooMAb® Recombinant Monoclonal Antibodies

Recombinant Antibodies Engineered for Greater Specificity, Higher Consistency, and Maximum Stability

Our ZooMAb® recombinant antibodies platform represents an entirely new generation of recombinant monoclonal antibodies that offer the superior specificity and affinity of a monoclonal and polyclonal combined with the flexibility of a recombinant for a wider selection of targets, formats, and species.

Highest Reproducibility and Performance

Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Each antibody is validated to reliably perform across multiple applications, including its most commonly used application.

Superior Quality of Rabbit Monoclonal Antibodies

Our first group of ZooMAb® antibodies are rabbit-derived, which can produce a large variety of desirable antibodies against “difficult” immunogens in mice, including small molecules (compounds of < 600 kDa), peptides, and antibodies specific for post-translational modification sites (PTM). By recognizing a higher diversity of epitopes per antigen at the picomolar level with high specificity, rabbit antibodies tend to provide excellent results in both standard assays and staining applications.

ZooMAB®  Antibodies: The Next Revolution

Maximum Stability and Convenience

Every ZooMAb® antibody is provided as a lyophilized product, individually packaged to provide long-term stability, faster shipping, and minimize non-value-added costs that typically incur through cold chain handling of liquids, including the thermal insulated packaging used in transportation. Therefore, every ZooMAb® antibody is exceptionally stable to allow for ambient shipping and storage if needed.

Maximum stability and convenience


Every ZooMAb® antibody is provided free of biocides like sodium azide or preservatives of animal origin, such as bovine serum albumin (BSA), and finished in a simple phosphate buffered saline (PBS) with trehalose. With ZooMAb® antibodies, complications arising from potentially hazardous materials or local safety restrictions are minimized and allow its use in both in vivo and in vitro applications.


Every ZooMAb® antibody is produced without the harm or sacrifice of animals. The proprietary recombinant expression system eliminates the need for arduous cell fusion and hybridoma construction, while providing greater specificity, affinity and reproducibility than monoclonal counterparts.

Multiple Pack Sizes for your Specific Need

Every ZooMAb® antibody is pre-aliquoted at 25 µL lyophilized equivalents to maximize product shelf life. Hence, you only purchase what you need and resuspend what you will use for your research.

Consistency for Each Application

ZooMAb® antibodies are recombinantly produced, purified and pre-aliquoted for you. Every antibody is tested in our own laboratory to work in at least 3 applications and ensured to perform the way you would expect it to in western blotting, immunofluorescence, and other common applications.

Consistency for each application


Enhanced Validation-Recombinant Antibody Technology
Immunofluorescent analysis of NIH 3T3 cells was performed using a 1:100 dilution of Cat. No. ZRB001906, Anti-ATRX, clone 2A12, ZooMAb® Rabbit Monoclonal and visualized with a Goat Anti-Rabbit secondary antibody conjugated to Alexa Fluor® 488 (Green). Actin filaments have been labeled with phalloidin (Red). Nucleus is stained with DAPI (Blue). This antibody positively stains the nucleus.

Immunohistochemistry (Paraffin)

Enhanced Validation-Recombinant Antibody Technology
Formalin Fixed Paraffin Embedded (FFPE) human prostate (A and B) tissue sections were prepared using heat-induced epitope retrieval (HIER). Immunostaining was performed using a 1:100 dilution of Cat. No. ZRB001906, Anti-ATRX, clone 2A12, ZooMAb® Rabbit Monoclonal. Reactivity was detected using a Goat Anti-Rabbit and DAB. Nuclear staining was observed in glandular cells of human prostate tissue sections.
