Products
Companion-animal rapid antigen/antibody test kits
Point-of-care lateral-flow test kits for detection of common companion-animal pathogens and antibody responses, intended for use in clinics, shelters and field settings.
Livestock in-field rapid test kits
Robust, field-ready rapid diagnostic kits for on-farm detection of livestock pathogens and herd-level screening with multi-pathogen options.
Food and feed safety ELISA kits and rapid screening assays
ELISA plate kits and lateral-flow rapid screening assays for detection of veterinary drug residues, mycotoxins and food-borne pathogens in food, feed and dairy matrices.
Reader-compatible immunoassay kits
Immunoassay kits developed to interface with instrument readers to improve consistency and provide quantitative or semi-quantitative outputs for clinical and veterinary use.

Services
Recombinant antigen and reagent development
Contract production and development of recombinant proteins and reagents used as capture and detection reagents in immunoassays.
Immunoassay and molecular assay design
Design and prototyping of immunoassays (lateral flow, ELISA, IFA) and molecular assays (PCR/NAAT) including multi-analyte formats and matrix-specific method development.
Reader-compatible assay integration and reader development
Co-development of assays optimized for use with optical/electronic readers to provide quantitative or semi-quantitative results and reduce user interpretation variability.
ELISA and immunofluorescence assay development
Laboratory-grade ELISA and IFA kit development and method optimization for quantitative testing in food/feed and veterinary diagnostic laboratories.
Sample preparation and matrix validation services
Development of sampling protocols, homogenization and extraction procedures and validation for specific matrices such as grains, nuts, milk, feed and feces to reduce interferences.
Application training and technical support
User training, technical documentation and troubleshooting for test implementation, sample handling, biosafety and interpretation of results.
