In Vivo Antibodies

Order in vivo grade antibodies — low endotoxin (≤1 EU/mg), azide-free, pH-optimized for direct injection. Functionally validated in murine models. Available in mg quantities. RUO

Why Researchers Choose abinScience

Application-Validated Rigorously tested for WB, IHC, IF, ELISA, and FC with supporting images and data on every product page.
High Specificity & Sensitivity Monoclonal and polyclonal options with validated target specificity, minimal cross-reactivity, and lot-specific titer data.
Broad Species Reactivity Covering human, mouse, rat, and additional species for translational and comparative research.
Multiple Conjugation Options Unconjugated, HRP, AP, biotin, FITC, PE, APC, and other fluorochrome conjugates ready for your workflow.
Original Manufacturer Quality In-house development from immunogen design to final QC — full traceability and batch consistency guaranteed.

How to Select the Right Product

  1. Target & Species: Confirm the target protein and host species reactivity (human, mouse, rat, or other). Check the datasheet for cross-reactivity data.
  2. Application: Select antibodies validated for your specific assay — WB, IHC (paraffin/frozen), IF, ELISA, or flow cytometry (FC).
  3. Clonality: Monoclonal for reproducibility and epitope specificity; polyclonal for broader epitope recognition and enhanced signal in WB/IHC.
  4. Conjugation: Choose unconjugated for maximum flexibility, or HRP/fluorochrome conjugates for direct detection without secondary antibodies.

Documents & QC Data

Download product datasheets, validation images (WB/IHC/IF/FC), CoA, and application protocols on each product page. All data is lot-specific.

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. 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.
