Frequently Asked Questions

Common questions from IVD manufacturers and R&D engineers about Sekbio's antibody raw materials.

What IVD antibody raw materials does Sekbio supply?

Sekbio supplies monoclonal antibodies, matched antibody pairs, polyclonal antibodies, recombinant proteins, and colloidal gold conjugates for lateral flow assay (LFA), ELISA, CLIA, and FIA diagnostic applications. The catalogue covers 200+ SKUs across cardiac, infectious disease, fertility, oncology, and metabolic biomarkers.

How do I select the right antibody pair for sandwich ELISA or lateral flow assay?

Sekbio's matched antibody pairs are pre-screened so that the capture antibody and detection antibody bind to non-overlapping epitopes on the target antigen. For sandwich ELISA, we provide optimal coating concentration and detection antibody dilution ranges. For lateral flow assay, conjugated detection antibodies are available ready-to-use. Contact our technical team for application-specific recommendations.

What is the minimum order quantity (MOQ) for IVD antibody raw materials?

The MOQ for Sekbio IVD antibody products is 1 mg. Larger quantities from 10 mg to gram scale are available for OEM production supply. Contact info@sekbio.com for volume pricing.

How does Sekbio ensure batch-to-batch consistency for IVD production?

All Sekbio antibodies are manufactured under ISO 13485 QMS with batch-to-batch CV below 10%. Each lot is tested for binding activity (≥90% of reference), purity (>90% SDS-PAGE), aggregation (<5% SEC-HPLC), and specificity (≥95%). A Certificate of Analysis (CoA) is provided with every shipment.

Which IVD detection platforms are Sekbio antibodies validated for?

Sekbio antibody raw materials are validated for POCT lateral flow assay (colloidal gold LFA), fluorescence immunoassay (FIA), enzyme-linked immunosorbent assay (ELISA), and chemiluminescence immunoassay (CLIA). Each product page specifies which platforms have been validated.

Can Sekbio develop custom IVD antibodies for a new biomarker target?

Yes. Sekbio's antibody service team develops custom monoclonal antibodies from new biomarker targets — covering antibody sequencing, sequence optimisation, CHO cell line expression, and purification to diagnostic grade in 8–12 weeks. Learn about our antibody development service or contact us to discuss your target.
