High-quality IVD antibody raw materials including monoclonal antibodies, polyclonal antibodies, recombinant proteins, and antibody pairs. All products are manufactured under ISO 13485 quality system with batch-to-batch consistency guaranteed.
High-affinity monoclonal antibodies optimised for IVD diagnostic testing — validated for CLIA, lateral flow assay, and ELISA platforms. Available in IgG/IgM isotypes with colloidal gold, fluorescence, and HRP conjugates.
Polyclonal antibodies with broad epitope coverage for high sensitivity in rapid test and ELISA applications. Ideal as detection antibodies in sandwich lateral flow assay formats.
Recombinant proteins expressed in CHO, HEK293, or E. coli — consistent quality for IVD assay development and scalable OEM production. Purity ≥95%, native and tagged variants available.
Pre-screened capture and detection antibody pairs for sandwich ELISA, CLIA, and lateral flow assay development. Matched pairs reduce assay development time from months to weeks.
Ready-to-use colloidal gold conjugated antibodies for lateral flow assay and fluorescence-labelled antibodies for FIA rapid test development.
