Pourquoi les chercheurs choisissent abinScience

Pureté ≥95% et faible taux d'endotoxines Typical ≤0.1 EU/µg verified by LAL assay. Lot-specific CoA with SDS-PAGE and SEC-HPLC data included.
Activité biologique vérifiée Functional validation via ELISA or cell-based proliferation/signaling assay. High batch-to-batch consistency (<20% CV).
Cinq systèmes d'expression HEK293 & CHO for native PTMs; E. coli for high-yield screening; insect and yeast for balanced cost and glycosylation.
Formats flexibles Carrier-free (no BSA), His-tagged, Fc-chimera, biotinylated; lyophilized or liquid — choose the best fit for your assay.
Extensible et fiable From µg to mg quantities with consistent lead times. Global cold-chain shipping with dry-ice packaging.

Comment sélectionner le produit approprié

Application :

Choose carrier-free for sensitive bioassays (e.g., CAR-T expansion, organoid culture, SPR). His-tag works best for pull-down and purification workflows.

Système d'expression :

Use HEK293/CHO for native glycosylation and disulfide bonds; E. coli for cost-effective high-throughput screening; insect/yeast when moderate PTMs are sufficient.

Tag et format :

His-tag for IMAC purification and binding studies; Fc-chimera for enhanced avidity and half-life; biotinylated for immobilization on streptavidin surfaces.

Endotoxine :

Match your assay tolerance — ≤0.1 EU/µg is recommended for immune cell culture and in vivo studies. Always verify via the lot-specific CoA.

FAQs

Que signifie « sans porteur » ?

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.

Quel système d'expression dois-je choisir ?

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.

Quel niveau d'endotoxine est recommandé pour les tests sur cellules immunitaires ?

≤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.

Comment reconstituer les protéines lyophilisées ?

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

Ces protéines sont-elles de qualité RUO ou de qualité GMP ?

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