Nucleotide Quantification Service
InquiryMetabolic flexibility and energy homeostasis are central to the study of obesity and its related comorbidities. At the molecular level, nucleotides and their derivatives—including ATP, GTP, cAMP, and cGMP—serve as the primary energy currency and signaling mediators that dictate adipocyte function, insulin sensitivity, and systemic inflammation.
Nucleotide Quantification Service for Obesity Research
Protheragen provides an industry-leading nucleotide quantification service specifically tailored for preclinical obesity research. By utilizing high-resolution analytical platforms, we enable researchers to map the energetic landscape of metabolic tissues, providing critical insights into how high-fat diets, genetic modifications, or pharmacological interventions alter cellular energy states. Our service is designed to bridge the gap between phenotypic observations in animal models and the underlying biochemical drivers of metabolic dysfunction.
Core Technologies
To ensure the highest level of sensitivity and specificity for metabolic research, Protheragen employs a multi-platform analytical approach. Our technology suite is specifically engineered to handle the unique challenges of nucleotide stability and complex tissue matrices:
- Targeted Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
Our primary platform for absolute quantification. We utilize LC coupled with electrospray Ionization (ESI) and tandem mass spectrometry to resolve structurally similar nucleotides (e.g., ATP vs. dATP) with picomolar sensitivity.
- Ion-Pair Reverse Phase Chromatography
Nucleotides are highly polar molecules that often exhibit poor retention on standard columns. We utilize specialized ion-pairing agents that temporarily modify the stationary phase, ensuring sharp peak resolution and the elimination of "ghost peaks" or co-elution.
- Stable Isotope Dilution (SID)
To account for potential matrix effects—particularly common in lipid-heavy adipose samples—we incorporate 13C- or 15N-labeled internal standards. This allows for precise normalization and the highest degree of quantitative accuracy.
- High-Resolution Mass Spectrometry (HRMS)
For discovery-based projects or when identifying unknown nucleotide derivatives and adducts, our Orbitrap-based systems provide the accurate mass measurement (sub-1-ppm) required for confident molecular formula assignment.
- Rapid Quenching & Cryogenic Processing
Beyond the instrumentation, our core technology includes a proprietary stabilization workflow. We utilize automated tissue homogenizers maintained at sub-zero temperatures to prevent the enzymatic hydrolysis of triphosphates into monophosphates during preparation.
- Bioluminescence Integration
For high-throughput screening of total cellular energy charge, we offer validated enzymatic bioluminescence assays that provide rapid, cost-effective readouts of the ATP:ADP:AMP ratio to complement our MS-based services.

Service Scope
Our quantification services cover a broad spectrum of metabolites essential for obesity research, including:
- Adenine Nucleotides
ATP, ADP, AMP, and the resulting energy charge ratios.
- Guanine Nucleotides
GTP, GDP, GMP, crucial for G-protein coupled receptor (GPCR) signaling in metabolic pathways.
- Cyclic Nucleotides
cAMP and cGMP, the secondary messengers for lipolysis and thermogenesis.
- Nucleotide Sugars
UDP-glucose, UDP-GlcNAc, and others involved in protein glycosylation and insulin resistance.
- Nicotinamide Adenine Dinucleotides
NAD+/NADH and NADP+/NADPH ratios, which are pivotal in redox balance and mitochondrial health.
Workflow
Protheragen maintains a rigorous five-stage workflow to ensure data integrity from sample reception to final reporting:
Fields of Application
The applications for nucleotide quantification in obesity research are vast:
- Adipocyte Thermogenesis: Measuring ATP/ADP ratios in brown adipose tissue (BAT) to assess UCP1-mediated uncoupling efficiency.
- Insulin Sensitivity Studies: Analyzing the role of nucleotide sugars in the hexosamine biosynthetic pathway and its impact on insulin receptor signaling.
- Mitochondrial Bioenergetics: Evaluating mitochondrial dysfunction in skeletal muscle or liver under high-fat diet conditions.
- Appetite Regulation: Quantifying cyclic nucleotides in hypothalamic tissue to study neuropeptide signaling.
- Inflammation and Purinergic Signaling: Monitoring extracellular ATP and adenosine levels in inflamed adipose tissue.
Advantages
Protheragen stands out by offering a specialized focus on Preclinical Metabolic Models. Our advantages include:
Unrivaled Sensitivity
Our platform is engineered to detect low-abundance signaling nucleotides—such as cAMP and cGMP—with industry-leading precision. We can generate robust data from small-volume needle biopsies, allowing researchers to preserve murine models for longitudinal studies rather than terminal sampling.
Tissue-Specific Optimization
Metabolic research often fails at the extraction phase due to "difficult" samples. We have perfected extraction methods for recalcitrant tissues, such as high-lipid content brown and white fat.
Absolute Quantification
While many labs offer relative profiling, Protheragen delivers exact molar concentrations. Unlike relative profiling, we provide exact molar concentrations, allowing for direct comparison across different study cohorts.
Expert Consultation
We do not just deliver spreadsheets; we deliver context. Every project is overseen by PhD-level biologists specializing in endocrinology and metabolic signaling. We assist in interpreting how specific nucleotide fluctuations correlate directly with phenotypes like weight gain, glucose intolerance, or impaired insulin signaling.
Advanced Methodological Equivalence
Our analytical framework provides a high-fidelity alternative to traditional tracer studies. By achieving exceptional cross-platform consistency with gold-standard radioactive methodologies, we deliver precise metabolic insights without the logistical constraints of radiopharmaceuticals, ensuring robust and reproducible data for complex preclinical trials.

Customer Review
Uncovering Critical Checkpoints in Hepatic Metabolism
"The team at Protheragen provided us with a level of detail we couldn't achieve in-house. Their ability to quantify the adenylate energy charge in our hepatic steatosis models allowed us to identify the exact metabolic checkpoint where our lead compound was acting. The data was publication-ready and incredibly robust."Dr. S.Z., Metabolic Disease Institute
Unmatched Expertise in Complex Adipose Tissue Analysis
"Working with Protheragen has been a seamless experience. Their expertise in handling lipid-rich adipose samples for nucleotide analysis is unmatched. We have already integrated their services into our upcoming preclinical safety studies and look forward to a long-term partnership."Dr. J.P., Biopharmaceutical Corp
Frequently Asked Questions
-
How do you prevent ATP degradation during shipping?
We provide specific protocols for flash-freezing in liquid nitrogen and shipping on dry ice. We also offer stabilized extraction buffers if pre-extraction at your site is preferred.
-
Can you handle samples from high-fat diet (HFD) mouse models?
Yes, our extraction protocols are specifically optimized to remove high levels of triacylglycerols that usually interfere with nucleotide analysis.
-
Do you offer cyclic nucleotide analysis separately?
While they can be part of a broad panel, we offer high-sensitivity targeted assays for cAMP and cGMP specifically for signaling studies.
-
How does this service compare to standard kits?
Kits are often non-specific and prone to background interference. Our LC-MS/MS method provides definitive molecular identification and absolute quantification.
-
Can you measure the NAD+/NADH ratio?
Absolutely. We use specialized cold-extraction to maintain the delicate balance of these redox pairs.
-
What is the typical turnaround time?
From sample receipt to the final report, our standard turnaround is 3–4 weeks.
-
Are your services applicable to cardiovascular research related to obesity?
Yes, we frequently analyze cardiac tissue to study metabolic remodeling in the context of obesity-induced heart failure.
-
Do you provide statistical analysis?
Yes, our reports include fold-change analysis, p-values, and PCA plots as standard.
-
Can I discuss my specific animal model with your scientists?
We encourage it. Our experts are available for pre-project consultations to ensure the study design is optimized for metabolic flux.
