When buying AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) for biochemical and metabolic research, verifying analytical purity and lot consistency is critical. PX1 Research supplies high-purity, US-manufactured AICAR verified via HPLC and mass spectrometry with batch-specific COAs for rigorous in vitro and preclinical experimentation.
Procuring research compounds for quantitative metabolic studies requires strict adherence to analytical quality standards. Principal investigators and laboratory procurement managers evaluating options for buying AICAR must prioritize high-performance liquid chromatography (HPLC) and mass spectrometry (MS) validation to prevent experimental artifacts caused by degraded reagents or synthesis side-products.
AICAR operates as a cell-permeable nucleoside analog that intracellularly phosphorylates into ZMP, an AMP mimetic. Because ZMP directly regulates AMP-activated protein kinase (AMPK) without altering intracellular ATP-to-AMP ratios, subtle impurities or chemical degradation can compromise binding affinity and enzymatic kinetics in vitro. Verifying sequence integrity, exact molecular weight (258.23 g/mol), and raw material purity is essential prior to assay integration.
To streamline vendor selection, research facilities should assess suppliers against standardized laboratory criteria to ensure reproducible experimental outcomes across all study phases.
Evaluating a potential AICAR shop requires examining analytical documentation and facility compliance standards. Below is a structural checklist comparing standard reagent suppliers against PX1 Research protocol requirements:
1. Purity Thresholds: Require ≥98% purity confirmed by RP-HPLC. Sub-standard reagents introduce synthetic precursors that skew phosphorylation assays. 2. Molecular Identification: Confirm structural identity via High-Resolution Mass Spectrometry (HRMS) matrix analysis for every batch. 3. Endotoxin Testing: Validate endotoxin levels below 0.01 EU/mg using Chromogenic LAL assays to ensure cell culture viability. 4. Analytical Transparency: Ensure third-party, lot-specific Certificates of Analysis (COAs) are publicly accessible prior to purchase. 5. Logistics & Storage: Confirm immediate cold-chain handling with domestic dispatch from ISO-compliant US facilities.
Facilities purchasing through our research peptides hub receive full batch documentation verifying structural identity, purity, and microbial compliance.
Identifying a trustworthy AICAR shop involves looking beyond surface-level claims and thoroughly inspecting batch-level analytical data. Many international distributors offer bulk biochemicals, but often lack batch-specific verification or utilize outdated analytical spectra that do not represent the current physical inventory.
At PX1 Research, every production batch undergoes independent ISO 17025 accredited laboratory testing. RP-HPLC analysis maps chemical purity profiles, ensuring the absence of unreacted intermediate compounds or related nucleoside degradation products. Concurrently, Electrospray Ionization Mass Spectrometry (ESI-MS) confirms exact monoisotopic mass, guaranteeing that researchers receive unadulterated AICAR research powder.
By enforcing strict analytical transparent standards across our complete catalog of all peptides, we eliminate lot-to-lot variance, enabling laboratory researchers to publish high-impact, reproducible data.

In preclinical metabolic modeling, AICAR serves as a primary pharmacologic tool for investigating the AMP-activated protein kinase pathway. Unlike physiological stressors like nutrient deprivation or exercise—which elevate intracellular AMP levels relative to ATP—AICAR bypasses the upstream adenylate kinase step.
Upon entering target cells via nucleoside transporters, adenosine kinase phosphorylates AICAR into 5-aminoimidazole-4-carboxamide ribonucleotide (ZMP). ZMP binds directly to the gamma subunit of AMPK at the allosteric AMP-binding sites. This binding event induces a conformational change that promotes phosphorylation of the catalytic alpha subunit at Thr-172 by upstream kinases such as LKB1.
Preclinical studies indicate that ZMP accumulation stimulates downstream catabolic pathways—including fatty acid oxidation and glucose transport—while inhibiting anabolic processes like lipogenesis and protein synthesis in isolated muscle tissue and hepatocyte cultures. Further mechanistic insights into metabolic regulation can be explored via our AMPK activation research guide.
Laboratory evaluation of AICAR spans diverse fields of metabolic research, cellular bioenergetics, and gene expression profiling. Rodent models and cell culture assays frequently employ AICAR to elucidate mechanisms of glucose homeostasis and mitochondrial remodeling.
1. Mitochondrial Biogenesis: In vitro assays utilizing skeletal myoblasts demonstrate that sustained AMPK activation via AICAR upregulates Peroxisome Proliferator-Activated Receptor Gamma Coactivator 1-Alpha (PGC-1α) transcription, driving nuclear-encoded mitochondrial gene expression. 2. Lipid Metabolism: Rodent models show that AICAR administration inactivates Acetyl-CoA Carboxylase (ACC) via site-specific phosphorylation, decreasing malonyl-CoA concentrations and accelerating mitochondrial beta-oxidation rates. 3. Glucose Transporter Translocation: Cell culture experiments confirm that AICAR-stimulated AMPK activation promotes GLUT4 vesicle translocation to the plasma membrane independently of insulin signaling pathways.
Investigators conducting comparative metabolic studies often pair AICAR experiments with assays involving mitochondrial peptides like MOTS-c to map overlapping metabolic signaling networks.
When designing preclinical protocols to study oxidative capacity and metabolic signaling, researchers frequently compare AICAR against other targeted metabolic modulators. While AICAR functions primarily via nucleoside phosphorylation and direct AMPK activation, alternative compounds engage distinct molecular targets within metabolic pathways.
For instance, Cardarine (GW501516) functions as a selective agonist of the Peroxisome Proliferator-Activated Receptor delta (PPARδ), activating genes responsible for fatty acid transport without direct AMPK phosphorylation. Similarly, Stenabolic (SR9009) targets the Rev-Erbα nuclear receptor to regulate circadian gene expression and metabolic rate.
In contrast, mitochondrial-derived peptides such as MOTS-c act upstream to regulate nuclear gene expression during metabolic stress. Understanding these mechanistic distinctions allows investigators to select the precise biochemical probe for their specific hypothesis testing.
Correct handling and reconstitution of lyophilized AICAR powder are critical to maintain structural stability and prevent non-specific precipitation during in vitro assays. AICAR is supplied as a lyophilized white powder that exhibits high solubility in aqueous media.
For stock solution preparation, researchers typically dissolve AICAR in sterile, deionized water, phosphate-buffered saline (PBS, pH 7.4), or dimethyl sulfoxide (DMSO). Aqueous stock solutions up to 50 mM can be prepared at room temperature with minimal gentle agitation. Avoid vigorous vortexing or sonication, which may introduce shear stress.
For cell culture application, stock solutions should be filtered using a sterile 0.22-micron polyethersulfone (PES) membrane filter prior to addition to culture media. Detailed reconstitution calculations and handling safety parameters can be reviewed in our comprehensive laboratory peptide research hub.
Lyophilized AICAR displays robust stability when maintained under controlled storage parameters. Upon receipt at your research facility, the sealed vial should be stored in a desiccated environment at -20°C for long-term storage, protected from light exposure.
Reconstituted liquid stock solutions stored at 4°C are stable for short-term use (up to 7 days). For extended analytical series, aliquot the reconstituted solution into sterile microcentrifuge tubes to prevent repeated freeze-thaw cycles and store at -80°C. Repeated thermal cycling accelerates ester hydrolysis and nucleoside degradation, which reduces active compound concentration over time.
All handling should occur within a certified biosafety cabinet or laminar flow hood using personal protective equipment (PPE), including nitrile gloves and lab coats, strictly following institutional safety protocols.
Cellular assays—particularly primary cell cultures and stem cell lines—are sensitive to bacterial endotoxin contamination. Lipopolysaccharides (LPS) induce inflammatory cytokine cascades that confound metabolic measurements and skew gene expression data.
