Infectious disease proteins are crucial for both diagnostics and therapeutics R&D. Whether they are supporting the development of a commercial detection kit or generating a custom antibody, these proteins need to meet their native structure and disease components. Therefore, kbDNA has assembled a comprehensive selection of recombinant and native antigens for various diseases. Our library selections include viral, bacterial, fungal and parasitic disease proteins from multiple strains and are validated via our QC process.
