What does “carrier-free” mean?

Carrier-free proteins contain no stabilizers (e.g., BSA), reducing interference in sensitive assays and enabling precise mass-based dosing. Ideal for SPR, BLI, and cell-based functional studies.

Which expression system should I choose?

HEK293/CHO: Native folding, glycosylation, and disulfide bonds — ideal for receptor-binding and functional studies.E. coli: High yield and cost-effective, best for structural screening.Insect/Yeast: Balanced PTMs with good scalability.

What endotoxin level is recommended for immune cell assays?

≤0.1 EU/µg is the standard for immune cell culture, T-cell expansion, and in vivo studies. Every lot ships with LAL-verified endotoxin data on the CoA.

How to reconstitute lyophilized proteins?

Use sterile, endotoxin-free buffer. Gently swirl — avoid vortexing. Aliquot into single-use volumes and store at -80°C to prevent freeze-thaw damage.

Are these proteins RUO or GMP-grade?

Unless explicitly labeled, all products are Research Use Only (RUO). For GMP-grade requirements, contact our team for custom manufacturing options.

Comment sélectionner le produit approprié

Cible et espèce :

Confirm the target protein and host species reactivity (human, mouse, rat, or other). Check the datasheet for cross-reactivity data.

Application:

Select antibodies validated for your specific assay — WB, IHC (paraffin/frozen), IF, ELISA, or flow cytometry (FC).

Clonalité :

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.

Documents et données de CQ

Download product datasheets, validation images (WB/IHC/IF/FC), CoA, and application protocols on each product page. Toutes les données sont spécifiques au lot.

FAQs

Comment vos anticorps sont-ils validés ?

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.

Proposez-vous des anticorps conjugués ?

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

Avec quelles espèces vos anticorps réagissent-ils ?

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

Quelle est votre politique de remplacement ?

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.

Puis-je obtenir des anticorps personnalisés ?

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