Cat (Felis catus) Research Reagents

Browse Cat (Felis catus) antibodies and recombinant proteins — species-validated reagents for veterinary medicine, comparative oncology, and infectious disease research. The domestic cat genome (~2.35 Gb, 21,865 protein-coding genes) shares extensive conserved synteny with the human genome, and over 250 naturally occurring hereditary diseases analogous to human disorders have been documented in cats, including hypertrophic cardiomyopathy (HCM), polycystic kidney disease (PKD), lysosomal storage disorders, and spinal muscular atrophy. Feline infectious agents — including feline immunodeficiency virus (FIV, a natural lentiviral model of HIV/AIDS), feline leukemia virus (FeLV), and feline coronavirus (FCoV/FIPV) — provide powerful spontaneous disease models for antiviral and vaccine development. Our reagents support research across veterinary diagnostics and clinical pathology, comparative genomics and breed-specific genetic disorders, feline retroviral and coronavirus biology, immune marker profiling (CD antigens, cytokines, immunoglobulins), and companion animal oncology. RUO

Species-Specific Validation Antibodies validated with confirmed reactivity to feline targets using species-appropriate positive controls from feline tissues, cell lysates, and serum samples.
Broad Target Coverage Feline immune markers (CD4, CD8, FoxP3), cytokines (feline IL-6, TNF-α, IFN-γ), immunoglobulins (IgG, IgA, IgM), signaling molecules, structural proteins, and infectious disease antigens.
Cross-Reactivity Data Detailed species cross-reactivity information provided on every product datasheet, enabling comparative studies across companion animal, veterinary, and human research contexts.
Multiple Applications Validated for WB, IHC, IF, ELISA, and FC across veterinary diagnostic, clinical pathology, and comparative medicine research workflows.
Original Manufacturer In-house production under ISO 9001 & ISO 13485 quality systems — reliable supply, consistent lot-to-lot performance, and lot-specific CoA and validation data on every product page.

FAQs

How are your antibodies validated?

Every antibody is validated in its listed applications (WB, IHC, IF, ELISA, FC) with supporting images and data on the product page. We use positive and negative controls plus knockout/knockdown verification where available.

Do you offer conjugated antibodies?

Yes — HRP, AP, biotin, FITC, PE, APC, Alexa Fluor, and other fluorochrome conjugates are available. Custom conjugation services are also offered for bulk orders.

What species do your antibodies react with?

Most antibodies target human, mouse, and rat. Many show validated cross-reactivity with additional species including cat. Check the product datasheet for confirmed reactivity data.

What is your replacement policy?

If a product does not perform as described under recommended conditions, contact us within 30 days for replacement or credit. Our technical team will help troubleshoot first.

Can I get custom antibodies?

Yes — our parent company AtaGenix offers full custom antibody development from immunogen design through hybridoma screening and scale-up production.

All products manufactured by AtaGenix Laboratories under ISO 9001 & ISO 13485 quality systems.
