5-Amino-1MQ 2mg — Vial Spec, Reconstitution Math & COA

Overview of 5-Amino-1MQ 2mg Vials & Product Availability

A 2mg vial of 5-Amino-1MQ contains exactly two milligrams of high-purity, lyophilized 5-amino-1-methylquinolinium salt. This specific mass unit is engineered for low-volume pilot experiments, assay standardization trials, or micro-dosing protocols in cellular research where maintaining solvent fresh-state integrity is critical. Laboratory teams frequently utilize 2mg configurations to execute quick single-plate in vitro screenings without subjecting larger master stocks to repeated thermal cycles or risk aqueous hydrolysis over extended benchtop periods.

While PX1 Research frequently produces custom pilot runs, our standard inventory emphasizes larger formats like the flagship 5-Amino-1MQ 5mg vial, which offers enhanced volumetric flexibility for multi-well high-throughput assays. Researchers seeking to review our comprehensive catalog of metabolic regulators, mitochondrial peptides, and custom synthesis options can browse our complete collection of all peptides and research compounds. Regardless of the target fill size, all compounds provided by PX1 Research are held to rigorous analytical standards to guarantee lot-to-lot consistency.

Molecular Identity and NNMT Inhibition Mechanism

5-Amino-1MQ (5-amino-1-methylquinolinium) is a selective, membrane-permeable small-molecule inhibitor targeting the cytosolic enzyme nicotinamide N-methyltransferase (NNMT). In eukaryotic cell populations, NNMT catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide (NAM), producing 1-methylnicotinamide (1-MNA) and S-adenosylhomocysteine (SAH). Because 1-MNA is an irreversible waste product excreted by the cell, elevated NNMT activity effectively depletes cellular nicotinamide pools, preventing its salvage back into nicotinamide adenine dinucleotide (NAD+).

Preclinical studies suggest that NNMT expression is upregulated in dysfunctional adipocytes and specific metabolic tissue lines. By inhibiting NNMT enzymatic activity, 5-Amino-1MQ prevents the methylation and subsequent clearance of nicotinamide. In vitro data indicate that this enzyme blockade preserves intracellular nicotinamide levels, driving the NAD+ salvage pathway via nicotinamide phosphoribosyltransferase (NAMPT). Elevated NAD+ concentrations subsequently enhance mitochondrial electron transport chain efficiency, upregulate sirtuin-1 (SIRT1) signaling, and promote fatty acid oxidation pathways within treated cellular models.

Reconstitution Calculations for 2mg Lyophilized Mass

Accurate reconstitution of a 2mg (2,000 micrograms) lyophilized cake requires precise volumetric measurement using sterile laboratory diluents such as bacteriostatic water, sterile water for injection, or phosphate-buffered saline (PBS). Because 5-Amino-1MQ possesses specific solubility parameters, researchers must calculate final stock concentrations based on total added liquid volume.

To achieve a standard 2.0 mg/mL concentration, dissolve the 2mg contents in exactly 1.0 mL of reconstituting solvent (2,000 µg / 1,000 µL = 2.0 µg/µL). If a lower working concentration is desired to minimize pipetting margin-of-error during micro-plate dosing, adding 2.0 mL of diluent yields a 1.0 mg/mL solution (1.0 µg/µL). Alternatively, adding 3.0 mL of solvent generates a 0.667 mg/mL concentration (0.667 µg/µL). To quickly simulate alternative working volumes, target molarities, or micro-dosing dilutions, research personnel should utilize the PX1 interactive reconstitution calculator.

Aliquot Planning & In Vitro Assay Protocol Design

In cell culture protocols—such as 3T3-L1 adipocyte differentiation assays or C2C12 myoblast respiratory tests—5-Amino-1MQ is typically introduced to culture media at micromolar (µM) working concentrations. When transitioning reconstituted liquid stock into culture media, working solution stability must be strictly managed to prevent precipitate formation or chemical degradation.

Following primary dissolution, the master stock solution should be divided into single-use micro-aliquots using sterile microcentrifuge tubes. Aliquoting eliminates the destructive cycle of freeze-thawing, which can destabilize the methylquinolinium structure and reduce enzymatic inhibition potency over time. For hydrophobic screening assays or serum-free cell models, primary dissolution in a minimal volume of dimethyl sulfoxide (DMSO) followed by dilution into aqueous buffer may be employed, provided DMSO solvent toxicity limits for the specific cell line are strictly observed.

Storage Protocols and Lyophilized Stability

Lyophilized 5-Amino-1MQ 2mg vials maintain maximum chemical stability when stored in dark, desiccated conditions at -20°C to -80°C. Sunlight and ambient humidity represent primary drivers of chemical degradation; therefore, vials should remain inside original light-blocking packaging until immediate laboratory preparation.

Once reconstituted into aqueous or buffered solutions, 5-Amino-1MQ should be stored at 2°C to 8°C if intended for immediate use within 24 to 48 hours. For long-term storage of reconstituted aliquots, solutions must be kept frozen at -20°C or colder for up to 90 days. Exposure to repeated freeze-thaw cycles, ambient temperatures above 25°C, or basic pH conditions accelerates degradation, potentially altering the effective inhibitor molarity during assay runs.

Quality Assurance, Lot-Matched Testing, and COA Verification

Every production lot of 5-Amino-1MQ manufactured for PX1 Research undergoes rigorous analytical verification within ISO 17025 accredited, independent testing facilities. We utilize High-Performance Liquid Chromatography (HPLC) coupled with Mass Spectrometry (MS) to verify molecular identity, structural integrity, and purity levels exceeding 98.0%.

Additionally, all lots undergo USP <85> bacterial endotoxin screening to ensure suitability for sensitive cell culture and animal tissue models where lipopolysaccharide contamination could confound metabolic measurements. Laboratory directors can review and download exact lot-matched analytical documentation by visiting our transparent COA database. Every order fulfilled by PX1 Research originates from our state-of-the-art facilities in California and Arizona, backed by same-day dispatch for orders finalized Monday through Friday prior to cut-off.

Comparative Energetic and Metabolic Research Compounds

When evaluating small molecules and peptides targeted at cellular energy expenditure, mitochondrial biogenesis, and lipid turnover, investigators frequently compare 5-Amino-1MQ against alternative pathways. For instance, while 5-Amino-1MQ operates primarily as an NNMT inhibitor to restore NAD+ pools, the mitochondrial-derived peptide MOTS-c targets nuclear transcription factors to promote metabolic homeostasis and insulin sensitivity in muscle tissue models. Similarly, synthetic estrogen-related receptor alpha (ERRα) agonists like SLU-PP-332 induce oxidative muscle fiber transformation via direct transcription upregulation, contrasting with 5-Amino-1MQ's enzymatic pathway modulation. For pituitary-axis secretagogue paradigms impacting growth axis kinetics, compounds like Tesamorelin offer distinct hormonal signaling mechanisms for lipid mobilization research. Cross-referencing these complementary tools within our research hub allows investigators to select the precise molecular target required for their experimental architecture.

Determining Ideal Vial Fill Sizes: 2mg vs. 5mg Formulations

Choosing between a 2mg pilot vial and a larger standard format like the 5mg vial depends primarily on experimental scale, assay duration, and subject group size. A 2mg vial is ideal for brief, exploratory pilot studies, initial dose-response curve establishing, or single-plate enzymatic assays where minimal compound waste is desired.

Conversely, long-term rodent feeding models or broad high-throughput cell culture screens benefit significantly from larger 5mg mass units or bulk order configurations available through our wholesale laboratory program. Utilizing larger single-batch fills across extended research projects minimizes batch variability and streamlines reconstitution scheduling across multi-week protocols.
