IgG-like vs. tandem scFv—which to choose?

IgG-like offers extended half-life and stability; tandem scFv is compact and ideal for TCEs. For better process stability, consider scFv-Fc or DART-like formats.

What is the optimal CD3 affinity?

Moderate CD3 affinity is typically preferred to achieve effective T-cell activation while minimizing background. Use EC50 and cytokine release data from cell models to guide selection.

Do these have Fc effector function?

Both Fc-silent and effector-enhanced versions are available. Fc-silent is standard for CD3 TCEs; effector-enabled can be selected for dual-blockade or ADCC/ADCP studies.

How to Select the Right Product

Target & Species : Rigorously tested for WB, IHC, IF, ELISA, and FC with supporting images and data on every product page.
Application : Select antibodies validated for your specific assay — WB, IHC (paraffin/frozen), IF, ELISA, or flow cytometry (FC).
Clonality : Monoclonal for reproducibility and epitope specificity; polyclonal for broader epitope recognition and enhanced signal in WB/IHC.
Conjugation : Choose unconjugated for maximum flexibility, or HRP/fluorochrome conjugates for direct detection without secondary antibodies.

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.
