Biological fluids collected from veterinary and large-animal species, including goat, hamster, horse, non-human primates, pig, sheep, bovine, rabbit, and other veterinary or research species, are valuable research specimens because they provide access to systemic physiology, organ function, immune responses, and molecular signatures associated with health and disease while preserving much of the complex molecular composition present at the time of collection, including proteins, metabolites, lipids, extracellular vesicles, cell-free nucleic acids, cytokines, hormones, and antibodies. These biological matrices are widely used in comparative biology, veterinary medicine, translational research, biomarker discovery, immunology, toxicology, pharmacokinetics, infectious disease research, reproductive biology, and regenerative medicine. Species selection depends on the biological question, as each model offers distinct anatomical, physiological, metabolic, and immunological characteristics relevant to both human and veterinary diseases.
Key Features
-
Comprehensive Biological Fluid Collection : Includes serum, plasma, whole blood, cerebrospinal fluid (CSF), urine, saliva, milk, bronchoalveolar lavage fluid (BALF), synovial fluid, aqueous and vitreous humor, and reproductive fluids, depending on the species.
-
Preservation of Native Molecular Components : Preserves biologically relevant proteins, metabolites, lipids, hormones, cytokines, extracellular vesicles, and cell-free nucleic acids.
-
Broad Multi-Omics Compatibility : Supports multi-omics analyses, including proteomics, metabolomics, lipidomics, extracellular vesicle characterization, and cell-free or extracellular nucleic acid analysis.
-
Suitable for Longitudinal Studies : Enables longitudinal sampling in many experimental animal models, with minimally invasive collection possible for selected biological fluids.
