Animal Amniotic Fluid Metabolomics Services
Amniotic fluid plays a significant role as a metabolomic substrate, reflecting fetal metabolism. The composition of lipids, phospholipids, urea, carbohydrates, and proteins in amniotic fluid changes during pregnancy and reflects the health of both the fetus and the mother. Our metabolomics analysis service, which utilizes amniotic fluid as the sample matrix, primarily relies on NMR, GC-MS, and LC-MS techniques to identify a wide range of low molecular weight compounds found in amniotic fluid. As a powerful high-throughput analysis method, this service primarily supports scientific research in the following areas:
- Animal Pregnancy Process Research
Metabolomic analysis of biomarker levels and changes in amniotic fluid can characterize each pregnancy cycle stage. BioVenic completes an in-depth assessment of the normal pregnancy process by monitoring changes in some typical metabolites, such as blood sugar, carnitine, amino acids, lactate/pyruvate (L/P) ratio, creatinine, and other metabolites. This helps to understand the mechanisms of animal fetal development and maternal health during pregnancy.
- Animal Prematurity and Underdevelopment
Untargeted metabolomics of amniotic fluid has been used in comprehensive studies to assess preterm birth. Our metabolomics service monitors high levels of common biomarkers, such as amino acids and their derivatives, as well as small molecule metabolites. This comprehensive assessment allows us to evaluate intramembranous inflammation, infection, and placental function. This assessment can be used to predict preterm birth and complications associated with prematurity, such as bronchopulmonary dysplasia. BioVenic's animal amniotic fluid metabolomics solutions also provide new high-throughput tools for researching immune status and targeted therapies during pregnancy.
- Disease-Relevant Animal Amniotic Fluid Metabolomics
BioVenic offers personalized amniotic fluid metabolomics services for research purposes. These services aim to discover novel biomarkers that can predict maternal diseases during pregnancy and assess fetal congenital diseases and overall health status. Metabolomics is a unique and reliable new tool that you can trust in the research on maternal nutrition during pregnancy.

Amniotic Fluid Metabolomics Applications
| Monitoring of Fetal Growth and Development | Untargeted metabolomics, combined with biochemical analysis of amniotic fluid samples, can effectively monitor, and prevent major issues in mammalian pregnancy, such as fetal loss and intrauterine growth restriction. |
| Metabolic Fingerprints in Pregnancy Complications | Studies evaluating the metabolomic information of amniotic fluid in animals can reveal metabolic changes in various stages of mammalian pregnancy and offer detailed metabolic fingerprints. |
| Feed Development for Pregnant Animals | Maternal overnutrition or undernutrition during animal pregnancy significantly affects embryonic development and has important consequences for later survival. Amniotic fluid metabolomics research explores the impact of maternal nutrition on amniotic fluid composition, providing a comprehensive description and valuable perspective. This research also offers a theoretical foundation for developing feed for pregnant animals. |
Related Research
In a study investigating how maternal nutrition influences intra-uterine foetal development, researchers utilized a pig model to evaluate the effects of maternal dietary chitosan oligosaccharide (COS) supplementation on foetal survival and growth at gestation day 35. By combining 1H NMR-based metabolomics with biochemical profiling of amniotic fluid (AF), the authors demonstrated that dietary COS intervention significantly enhanced both the foetal survival rate and foetal size.Metabolomic and biochemical analyses of the amniotic fluid revealed profound diet-induced shifts in the foetal metabolic microenvironment. Specifically, maternal COS inclusion modulated key discriminatory metabolites involved in energy metabolism, amino acid metabolism, and carbohydrate utilization. The optimization of essential amino acid profiles and energetic substrates in the AF provided crucial nutrient support for rapid cellular proliferation and embryonic development. Overall, this study demonstrates that amniotic fluid metabolomics offers novel molecular insights into diet-regulated foetal growth, highlighting maternal COS supplementation as an effective nutritional strategy to mitigate early embryonic mortality and promote foetal health in swine and translational mammalian models.

Frequently Asked Questions
Q1: What are the primary sample requirements and collection guidelines for animal amniotic fluid metabolomics?
A: To ensure high-quality metabolomics data, amniotic fluid samples should be collected under sterile conditions to avoid contamination by maternal blood, urine, or cellular debris. Immediately after collection, centrifuge the sample at low speed to remove suspended cells and particulate matter. Aliquot the clear supernatant into sterile, pre-chilled polypropylene microcentrifuge tubes, flash-freeze them in liquid nitrogen, and store them at -80°C. For minimum volume recommendations or specific additives depending on your target animal species, please contact our technical support team to confirm details before sample collection.
Q2: Which analytical platform should I choose: LC-MS/MS or GC-MS for amniotic fluid metabolomics?
A: The choice of platform depends on your target metabolites and research goals. Liquid Chromatography-Mass Spectrometry (LC-MS/MS) offers broad coverage for polar, semi-polar, and lipid species, making it ideal for comprehensive, non-targeted profiling. Gas Chromatography-Mass Spectrometry (GC-MS) excels at detecting volatile and low-molecular-weight metabolites, such as organic acids and sugar alcohols, though it requires chemical derivatization. We also offer targeted metabolomics for specific metabolite panels. For tailored advice on selecting the optimal analytical approach for your specific experimental design, please reach out to our technical support team.
Q3: How do you handle potential interference from high protein or salt concentrations in amniotic fluid?
A: Amniotic fluid contains proteins, electrolytes, and other endogenous components that can interfere with mass spectrometry by causing ion suppression or chromatographic column fouling. We utilize optimized, standardized protein precipitation and metabolite extraction protocols tailored for biofluid samples. These steps remove high-molecular-weight proteins while maximizing the recovery of small-molecule metabolites. If your samples require specialized pretreatment due to specific animal models or unusual matrices, we recommend consulting our technical support team to customize an extraction protocol prior to sample shipment.
Q4: What standard bioinformatics outputs are included in the animal amniotic fluid metabolomics service?
A: Our comprehensive data analysis deliverable includes raw data processing (peak alignment, feature extraction, and background subtraction), compound identification against updated spectral databases, and univariate/multivariate statistical analyses (such as PCA, PLS-DA, and volcano plots).
