Overview of SLU-PP-332 15mg Vial Specifications & Lab Utility
The 15mg vial configuration of SLU-PP-332 represents a high-mass research presentation designed specifically for laboratory settings requiring consistent, repeat-dosing protocols or parallel in vitro screens. Formulated as a sterile, lyophilized cake, each vial contains precisely 15 milligrams of active SLU-PP-332 compound, characterized by high solubility in organic co-solvents and suitable aqueous buffers. Principal investigators selecting the 15mg mass typically execute multi-week rodent metabolic assays, cell culture titration series, or high-throughput enzymatic screens where maintaining consistent batch chemistry across all replicates is paramount.
When planning laboratory inventory, matching chemical mass to experimental throughput prevents unnecessary degradation associated with repeated freeze-thaw cycles of reconstituted solution. For laboratories conducting lower-volume exploratory pilot studies, smaller vial options or specialized delivery formats—such as SLU-PP-332 capsules 250mcg—may be utilized depending on the established protocol. Exploring our complete collection of all peptides allows researchers to select the exact quantity and format necessary to meet specific institutional review board (IRB) or institutional animal care and use committee (IACUC) experimental parameters.
Molecular Mechanism & ERR Receptor Target Profile
SLU-PP-332 functions as a potent, synthetic pan-agonist of the Estrogen-Related Receptor (ERR) family, specifically demonstrating high affinity for ERRα, ERRβ, and ERRγ isoforms. Unlike classical estrogen receptors (ERα and ERβ), ERRs are orphan nuclear receptors that do not bind endogenous estradiol but act as key transcriptional regulators of cellular energy metabolism, mitochondrial biogenesis, and fatty acid oxidation. In vitro ligand-binding assays demonstrate that SLU-PP-332 directly binds to the ligand-binding domain (LBD) of ERRα, inducing a conformational change that facilitates co-activator recruitment, notably peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α).
Preclinical studies in murine models indicate that ERR activation by SLU-PP-332 upregulates a broad network of target genes involved in the Krebs cycle, oxidative phosphorylation, and mitochondrial electron transport chain function. In rodent tissue analysis, administration of ERR agonists has been documented to increase slow-twitch, oxidative muscle fiber composition without requiring prior physical endurance training. This metabolic reprogramming elevates baseline oxygen consumption rates (OCR) in isolated myocytes and shifts cellular substrate preference toward fatty acid oxidation, making SLU-PP-332 a critical tool in cellular bioenergetics research.
Reconstitution Mathematics for 15mg Mass
Accurate concentration calculations are vital for ensuring reproducible dosing in animal models and precise molar concentrations in cell culture media. When working with a 15mg (15,000 micrograms) lyophilized cake, researchers must select diluent volumes based on target stock concentration and volumetric accuracy limits of laboratory pipettes. Reconstitution should be performed using aseptic technique within a certified laminar flow hood, introducing sterile laboratory-grade diluents such as bacteriostatic water, sterile normal saline, or a small percentage of DMSO/PEG400 if required by solubility parameters.
The mathematical relationship between diluent volume and final stock concentration for a 15mg vial is detailed below: • 1.0 mL Diluent Volume: Yields a concentration of 15.0 mg/mL (15.0 μg/μL, or 15,000 μg/mL). • 2.0 mL Diluent Volume: Yields a concentration of 7.5 mg/mL (7.5 μg/μL, or 7,500 μg/mL). • 3.0 mL Diluent Volume: Yields a concentration of 5.0 mg/mL (5.0 μg/μL, or 5,000 μg/mL). To rapidly calculate custom stock concentrations, micro-molar conversions, or adjusted diluent volumes for specific multi-well plate setups, researchers are encouraged to utilize our interactive reconstitution calculator.

Aliquoting Protocols & Thermal Stability in Solution
Maintaining chemical stability following reconstitution is critical to avoiding hydrolysis, oxidative degradation, or passive precipitation out of solution. Once the 15mg lyophilized cake is fully dissolved, the primary stock solution should be immediately aliquoted into sterile, polypropylene micro-centrifuge tubes or low-protein-binding cryovials. Aliquoting reduces the risk of contamination and eliminates repeated freeze-thaw cycles, which can fragment molecular structure and reduce effective concentration over time.
Lyophilized vials should be stored at -20°C for short-term preservation or -80°C for long-term storage, protected from direct light exposure. Once reconstituted, aqueous stock solutions should be kept refrigerated at 2°C to 8°C if used within 72 hours. For extended experimental timelines, aliquots must be flash-frozen in liquid nitrogen and maintained at -80°C.

Analytical Verification: Lot-Matched HPLC, Mass Spectrometry & Endotoxin Testing
PX1 Research enforces strict quality control standards on all research compounds. Every lot of SLU-PP-332 undergoes rigorous identity, purity, and safety verification by independent, ISO 17025 accredited analytical laboratories. High-Performance Liquid Chromatography (HPLC) is conducted to verify a chemical purity profile exceeding 98.0%, ensuring that micro-impurities or synthesis by-products do not interfere with downstream cellular assays.
In addition to HPLC purity, Mass Spectrometry (MS) is performed to confirm exact molecular weight and structural identity. Endotoxin testing via Limulus Amebocyte Lysate (LAL) assays ensures that endotoxin levels remain strictly below <0.01 EU/mg, preventing unwanted immune activation or non-specific inflammatory signaling in delicate cell lines or animal tissues.

Comparative Analysis: SLU-PP-332 vs. GW501516 and SR9009 in Metabolic Assays
When designing protocols focused on cellular bioenergetics, endurance mimetics, and lipid oxidation, researchers often evaluate SLU-PP-332 alongside other established nuclear receptor ligands. While all these compounds modulate metabolic gene expression, their molecular targets and downstream physiological mechanisms differ significantly.
SLU-PP-332 acts directly as a pan-agonist of the ERR family (ERRα/β/γ), activating PGC-1α co-activation pathways without requiring upstream kinase stimulation. In contrast, compounds such as GW501516 (Cardarine) target the Peroxisome Proliferator-Activated Receptor delta (PPAR-δ), driving fatty acid transport and beta-oxidation gene expression via distinct nuclear response elements. Meanwhile, compounds like SR9009 (Stenabolic) operate as synthetic Rev-ErbA agonists, modulating circadian rhythms and mitochondrial content through transcriptional repression mechanisms. Evaluating these distinct pathways within comparative peptides for metabolic research models allows investigators to isolate specific transcriptional cascades responsible for mitochondrial remodeling.
Selecting Optimal Mass: 15mg Vial vs. Alternate Experimental Formulations
Choosing the correct product mass depends entirely on the design, scale, and duration of the planned research protocol. A 15mg vial offers substantial mass efficiency for laboratories conducting high-concentration cell culture treatments or multi-animal rodent cohorts over several days. Utilizing a single 15mg vial for an entire experimental block minimizes batch-to-batch variation, ensuring that every subject or culture well receives compound from an identical synthesis lot.
Conversely, for single-dose exploratory assays or small-scale pilot studies, a 15mg mass may yield excessive dissolved stock that risks degradation if stored beyond stability limits. In such scenarios, smaller mass options or pre-formulated solid-dose variants such as SLU-PP-332 capsules 250mcg provide convenient, precision-measured alternatives for non-parenteral or oral administration research models. Evaluating target sample size and solvent limits prior to ordering ensures optimal resource allocation.
