Polyamine Analysis Service
InquiryPolyamines, including putrescine, spermidine, and spermine, are low-molecular-weight polycationic aliphatic amines essential for cellular proliferation, differentiation, and metabolic homeostasis. Operating as dynamic rheostats of cellular vitality, these molecules exert profound influence over nucleic acid stability, protein synthesis, and mitochondrial bioenergetics. Their rapid interconversion and tight regulatory flux enable cells to adapt to oxidative stress and nutrient fluctuations, making them indispensable mediators of systemic metabolic health.
Comprehensive Polyamine Analysis Service for Obesity Research
In the context of obesity research, polyamine metabolism is intricately linked to adipogenesis, systemic inflammation, and energy expenditure. Disruptions in the polyamine pathway often correlate with metabolic syndrome, insulin resistance, and altered gut microbiota composition. Protheragen provides a specialized polyamine analysis service designed to decode these complex metabolic signatures. Our platform empowers preclinical researchers to quantify polyamine fluctuations in diverse biological matrices, offering critical insights into the mechanisms of lipid accumulation and metabolic reprogramming.
Core Technologies
To address the challenges of analyzing highly polar and low-abundance polyamines, Protheragen utilizes state-of-the-art analytical platforms.
- Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS/MS)
Our primary platform employs UHPLC-MS/MS. This system provides superior sensitivity and selectivity, allowing for the detection of polyamines at picomolar levels even in complex fatty tissues.
- Chemical Derivatization Strategies
Due to the lack of chromophores in polyamines, we utilize advanced derivatization (e.g., benzoylation or dansylation) to enhance ionization efficiency and chromatographic retention, ensuring robust and reproducible data.
- Isotopically Labeled Internal Standards
We employ stable isotope-labeled analogs for every target analyte to correct for matrix effects and recovery losses, providing absolute quantification rather than relative abundance.

Service Scope
Protheragen offers a versatile range of polyamine profiling options specifically calibrated for metabolic research:
- Primary Polyamines
Absolute quantification of putrescine, spermidine, and spermine.
- Acetylated Derivatives
Measurement of N1-acetylspermidine and N1-acetylspermine, crucial indicators of polyamine catabolism and metabolic stress.
- Precursor Analysis
Tracking levels of ornithine and L-arginine to map the flux through the urea cycle and polyamine biosynthetic pathways.
- Matrix Versatility
Validated protocols for white/brown adipose tissue (WAT/BAT), liver, hypothalamus, skeletal muscle, plasma, and gut microbiome samples.
Workflow
Our streamlined service process is designed to ensure maximum data integrity from sample receipt to final reporting.
Fields of Application
Our polyamine analysis service serves as a pivotal diagnostic bridge, translating complex metabolic flux into actionable data across diverse preclinical arenas, from adipocyte signaling to gut-brain axis modulation.
- Adipocyte Differentiation: Investigating how polyamine depletion or supplementation affects the transition from pre-adipocytes to mature, lipid-storing cells.
- Gut-Brain Axis Research: Analyzing fecal polyamines to determine how microbiota-derived metabolites influence host satiety and energy balance.
- Therapeutic Screening: Evaluating the impact of anti-obesity drug candidates on polyamine flux and mitochondrial function.
- Inflammation & Macrophage Polarization: Studying the polyamine pathway's role in shifting adipose tissue macrophages from a pro-inflammatory M1 phenotype to an anti-inflammatory M2 phenotype.
Advantages
Choosing Protheragen for your obesity-related polyamine research provides several distinct advantages:
High Sensitivity in Lipid-Rich Samples
Obesity Models present a unique analytical challenge: lipid-rich adipose tissue often leads to significant matrix suppression. Our proprietary extraction protocols are specifically engineered to mitigate these effects, ensuring high-sensitivity detection and consistent recovery rates even in challenging samples.
Pathway-Centric Insights
We provide more than just raw concentrations; we provide biological intelligence. Our "pathway-centric" reporting maps polyamine flux to critical metabolic regulators such as AMPK, PPAR-γ, and SIRT1, helping you visualize how your compound influences cellular energy homeostasis.
Validated Functional Profiling
Our analytical platform is optimized to evaluate the potent metabolic effects of spermidine, offering high-sensitivity detection of its role in autophagy-mediated weight loss and the systematic reduction of inflammatory markers in preclinical obesity models.
Rapid Turnaround
In the competitive landscape of drug discovery, timing is everything. We offer a streamlined workflow designed for the pace of preclinical development, providing rapid turnaround times and agile reporting.

Customer Review
Unlocking Metabolic Insights in Hepatic Steatosis
"Working with Protheragen has been transformative for our study on hepatic steatosis. Their ability to accurately measure N1-acetylspermidine in fatty liver samples provided the missing link in our understanding of how our lead compound modulates energy expenditure. The technical depth of their reports is unmatched."Dr. S. D., Metabolic Diseases Research Institute
Precision Profiling for Adipose Tissue Transformation
"We struggled with inconsistent polyamine data from other providers due to the complexity of our adipose tissue samples. Protheragen delivered highly reproducible results and helped us map the polyamine flux during the browning of white fat. We look forward to our next collaboration on gut microbiota metabolites."Dr. L. S., Biopharmaceutical Discovery Group
Frequently Asked Questions
-
Why is polyamine analysis critical for obesity research?
Polyamines regulate translation and autophagy; their decline is often linked to age-related obesity and metabolic dysfunction.
-
What sample volume is required?
Typically, 50-100 μL of plasma or 20-50 mg of tissue is sufficient for a comprehensive profile.
-
Can you distinguish between acetylated and non-acetylated forms?
Yes, our UHPLC-MS/MS method provides distinct separation and quantification for both.
-
Do you provide services for human clinical trials?
No, Protheragen focuses exclusively on preclinical research and discovery services.
-
How do you handle the high lipid content in obese mouse tissues?
We use specialized delipidation steps during extraction to ensure clean samples and prevent column fouling.
-
Are your results reproducible across different batches?
We use internal standards and QC samples in every run to ensure the inter-day and intra-day coefficient of variation (CV) remains below 15%.
-
Can polyamine levels be used as biomarkers for metabolic health?
Yes, specific ratios (e.g., spermidine/spermine) are often used in preclinical models to assess metabolic vigor.
-
What is the stability of polyamines in stored samples?
Polyamines are stable at -80°C, but we recommend adding an acid stabilizer (like perchloric acid) during initial processing.
-
Do you offer bioinformatic support?
Yes, we provide PCA plots, heatmaps, and pathway enrichment analysis as part of our advanced reporting.
