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.

適切な製品の選び方

標的と交差種:

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

用途:

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

クローン性:

Monoclonal for reproducibility and epitope specificity; polyclonal for broader epitope recognition and enhanced signal in WB/IHC.

コンジュゲーション:

Choose unconjugated for maximum flexibility, or HRP/fluorochrome conjugates for direct detection without secondary antibodies.

ドキュメントとQCデータ

Download product datasheets, validation images (WB/IHC/IF/FC), CoA, and application protocols on each product page. すべてのデータは特定のロットに固有です。

よくある質問（FAQ)

抗体はどのように検証されていますか？

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.

コンジュゲート抗体は提供していますか？

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

抗体はどの種と反応しますか？

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

交換ポリシーは何ですか？

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.

カスタム抗体は入手できますか？

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