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.
