About Us

Good Biotech Corp., an unprecedented duck IgY(ΔFc) antibody inventor and diagnostics manufacturer, has successfully built up the proprietary technology platform by using ducks as bioreactors to produce and develop novel polyclonal IgY(ΔFc) antibodies into various Biotechnology as well as biotherapeutics applications, including Immunodiagnostics, IgY(ΔFc) antibody derived therapeutic antibodies, functional health foods and oral health products. We are the only one company with the capability to rapidly mass production duck IgY(ΔFc) antibodies from hyper-immune duck eggs on an industrial scale. Good Biotech, also a professional polyclonal antibody manufacturer, has supplied quality rabbit/goat antibodies to worldwide customers, especially to Japan market for almost 30 years. We are the very first company to successfully develop and commercialize avian-antibody based immunodiagnostic assay kits, certified by FDA 510(k) (USA) and CE Marking (Europe). Thanks to the unique characteristics of duck IgY(ΔFc) antibody, this new generation antibody based immunodiagnostic kits has been recognized by our customers to be one of the best reagents in the world. Having the advantages such as free from common interferences, the performance including the sensitivity, precision, and accuracy can be highly improved by using duck IgY(ΔFc) antibodies as the materials of immunodiagnostic reagents; therefore, the performance of the kits is much superior than most of the current kits that are made from mammalian antibodies on the market.




Research and Development

Good Biotech is dedicated to continuously improve our products and develop solutions to address unmet medical needs.

The technology platform for production and the applications of duck IgY(ΔFc) antibodies is solely owned by Good Biotech Corp. and the patents have been granted worldwide including all the major and dominant markets. This proprietary technology has been successfully applied to biotherapeutic applications which address to high unmet medical needs: IgY(ΔFc) Antibody derived Biotherapeutics. We have gained promising results on the development of duck IgY(ΔFc) antibody derived snake antivenoms, digoxin specific antibody Fab fragment, neutralizing antibodies against pathogens of bacteria, virus, including SARS, Rotavirus, oral administration products, such as Anti-obesity, Caries-prophylaxis (anti-S.Mutans IgY (ΔFc) antibody), functional healthcare for prevention and reduction infections GI diseases (e.g., Norovirus, H. pylori, Enterovirus, Rotavirus).

Anti-snake venom IgY(ΔFc) antibodies: Good Biotech supplied several kinds of anti-snake venom IgY(ΔFc) antibodies, such as Cobra (Naja atra) venom, Krait (B. multicinctus) Venom, Vipera russellii formosensis antivenom, Bothrops jararaca venom (Pit viper venom) and Cobra & Krait venom to Center of Disease Control (CDC) Taiwan for their research. According to CDC Taiwan’s studies, Good Biotech's duck antivenoms are much superior than classical equine based snake antivenoms in terms its quality, efficacy, safety and cost of production.

Co-development anti-SARS IgY(ΔFc) antibody with Academia Sinica:

According to the results of the in-vitro experiments conducted in Academia Sinica, the neutralization effect of IgY(ΔFc) antibody against SARS virus was wonderful. The performance was far superior to the anti-SARS antibodies from horse serum or rabbit serum.

Production of duck IgY(ΔFc) antibody derived neutralizing antibodies are cost effective, conforming to the expectation of animal protection organizations, and is timely in view of the World Health Organization (WHO)'s current initiative to review the quality, efficacy and safety of therapeutic antibodies.


Good Biotech focuses on creating innovative diagnostic solutions that enable effective diagnosis and to improve healthcare.

Good Biotech’s Whole Blood CRP LIT Assay for POCT, being developed for the quantitative measurement CRP in human whole blood, serum or plasma, is able to obtain fast, accurate and reliable rest results within 2-3 minutes.

Newly launched, One-Step, Visual Snake Venom Rapid Test Kit: The kit is the one and only one diagnostic kit in the world for One Step Rapid Detection (3-5 minutes) of snake venom for medical emergency use. This new generation Snake Venom Rapid Test Kit is much quicker than current methods (eg. ELISA) and can give victims & healthcare professional information needed to act more precisely and effectively in making life-saving decisions.
