FAQs

What formats are available for this target?

Recombinant proteins in His-tagged, Fc-chimera, Avi-tagged, and biotinylated formats. Antibodies available unconjugated and in common conjugates.

Are your proteins suitable for SPR/BLI binding assays?

Yes. Our Avi-tagged and biotinylated proteins are optimized for surface immobilization in SPR (Biacore) and BLI (Octet) kinetics studies.

Do you offer matched pairs for PK/ADA assays?

Yes — we provide validated capture/detection antibody pairs and calibrator proteins for pharmacokinetic and immunogenicity ELISA development.

What lot-to-lot consistency can I expect?

Rigorous QC ensures <20% CV in bioactivity across lots. Every lot ships with CoA including SDS-PAGE, SEC-HPLC, and functional assay data.

Can I order in bulk for GLP/GMP studies?

We offer bulk quantities with enhanced documentation for regulated studies. Contact us for custom quotes and timelines.
