Description Mouse Cerebrospinal Fluid (CSF) is a clear physiological fluid that surrounds the brain and spinal cord, acting as a crucial mechanical cushion and playing a vital role in the clearance of metabolic waste from the central nervous system. Our standard mouse CSF is supplied as a mixed-gender, pooled matrix collected exclusively from healthy, Specific Pathogen Free (SPF) animals. In preclinical research, murine CSF is an essential biological matrix for neurobiology studies, biomarker quantification, and pharmacokinetic/pharmacodynamic (PK/PD) assessments. Due to the extremely low yield from individual mice, our CSF products are pooled from multiple genetically and environmentally matched animals. This pooling strategy not only provides sufficient volume for commercial assays but also establishes a stable, generalized biological baseline for reliable experimental data.For custom collections tailored to a specific gender, age, strain, or disease model, please contact us. Features SPF Grade Sourcing: Animals are sourced exclusively from highly controlled, Specific Pathogen Free (SPF) breeding colonies to ensure health status and sample reliability. Specialized Collection: Extracted via cisterna magna puncture by skilled technicians to minimize tissue damage compared to other extraction methods. Pooled for Consistency: Standard lots are pooled from strictly age-matched, mixed-gender animals to minimize individual biological variance. Preserved Integrity: Snap-frozen immediately post-collection to preserve native protein profiles and enzymatic activity. Colorless & Clear Matrix: Each sample is carefully evaluated macroscopically during collection to maintain a pure, colorless appearance and exclude samples with visibly evident RBC contamination. Strains All mouse CSF products are supplied as pooled samples (Mixed Gender) in standard 100 µL aliquots. C57BL/6: The standard wild-type background for transgenic Alzheimer's and Parkinson's disease models. CD-1 (ICR): A widely used outbred strain, ideal for general toxicology and PK/PD profiling.BALB/c: Commonly utilized for immunology and oncology baseline models. KM (Kunming): A highly valued outbred strain frequently used in pharmacological screening. Storage Store strictly at -80°C upon receipt. Avoid repeated freeze-thaw cycles. If the entire 100 µL vial will not be used in a single experiment, we strongly recommend aliquoting the fluid into smaller working volumes immediately after the first thaw. Shipping Ships globally on Dry Ice to guarantee sample integrity during transit. FAQ Q: Why do you sell pooled mouse CSF instead of individual samples?A single adult mouse yields only approximately 5–10 µL of CSF. Pooling samples from a group of matched animals provides a usable commercial volume (100 µL) and helps establish a stable biological baseline for sensitive downstream assays. Q: How do you check for blood contamination in the CSF?We rely on stringent macroscopic visual inspection. During the extraction process, our technicians carefully examine each sample against a pure white background. Any sample showing a visible pink tint—indicating obvious RBC contamination—is discarded and not included in the final pool. Q: What specific customizations do you offer for mouse CSF collections?A: We provide comprehensive customization options tailored to your precise experimental design. You can specify exact age requirements (defined by weeks or months), single-gender groups (strictly all-male or all-female), specific sub-strains, or customized dietary interventions (e.g., high-fat diet models). Q: Can you provide CSF from specific disease models?A: Yes. We can accommodate custom collections from validated disease models, including neurodegenerative transgenic models (such as Alzheimer's or Parkinson's) and metabolic disease models. Please note that due to the complex breeding cycles, extended maintenance, and lower availability of these cohorts, disease model CSF is priced at a premium compared to wild-type strains. Please contact our technical team in advance to discuss timelines and receive a custom quote. Q: Do you support CSF extraction from individual animals, or are all products pooled?A: While our standard catalog products are pooled to ensure a stable baseline and a practical commercial volume (100 µL), we do offer individual animal extractions (non-pooled, single-animal aliquots) as a custom service. Please keep in mind that a single adult mouse typically yields only 5–15 µL of CSF. Furthermore, demanding higher extraction volumes per animal significantly increases the risk of microscopic blood contamination. As a result, the significant loss of material and intensive labor directly increase the overall cost, making individual collections considerably more expensive than our standard pooled lots.
