Royal GD can support your livestock business with diagnostics products. Our positive control sera are produced from naturally infected or vaccinated animals with significant antibody levels. These sera are available as assay-independent controls or ‘in-house’ controls for monitoring the performance of third-party immunodiagnostic assays on a day-to-day basis.

The Chicken reference serum 98308 (CRS) can be used for monitoring day-to-day variation in poultry antibody ELISAs. The serum is produced by GD and the CRS contains significant and known antibody levels against several major avian pathogens. A Certificate of Analysis is provided, giving specificity data and target titres for the different assays used. Our assays, antigens and antisera
