Rat biological fluids are widely used in preclinical research because they provide minimally invasive access to systemic and organ-specific physiological processes while reflecting the complex molecular composition of the in vivo environment. Commonly studied specimens include serum, plasma, whole blood, cerebrospinal fluid (CSF), urine, bronchoalveolar lavage fluid (BALF), synovial fluid, saliva, milk, and reproductive fluids. These biological matrices contain proteins, metabolites, lipids, hormones, cytokines, extracellular vesicles, and nucleic acids that are routinely analyzed in toxicology, pharmacology, neuroscience, cardiovascular research, renal physiology, metabolic disease, inflammation, and biomarker discovery.
Key Features

-
Broad Multi-Omics Compatibility : Compatible with proteomics, metabolomics, lipidomics, transcriptomics, and immunoassays.
-
Translational Biomarker Resource : Provide biomarkers with translational potential for preclinical drug development and disease mechanism studies.
Typical Research Applications
-
Drug metabolism and toxicology: safety assessment, pharmacokinetics, and exposure studies.
-
Neuroscience: CSF biomarker discovery and neuroinflammation research.
-
Cardiovascular research: circulating biomarkers of cardiovascular injury, vascular biology, and cardiac remodeling.
