Product Overview

Methylene Blue is a synthetic phenothiazine-derived heterocyclic compound with a long-standing history in biochemical and cellular research. Its remarkable autoxidizable character enables it to function as a reversible electron donor and acceptor within biological systems, making it a uniquely versatile tool for studying mitochondrial respiration, redox-mediated signaling cascades, and neuroenergetic dynamics. The Peptide Store supplies this well-characterized metabolic research agent in a standardized encapsulated configuration engineered for precision, consistency, and longitudinal laboratory utility. Researchers across biochemistry, neuroscience, and cellular biology disciplines will find this 60-capsule platform an exceptionally reliable vehicle for in vitro profiling and metabolic flux tracking.

Peptide Structure & Amino Acid Sequence

Methylene Blue is not a peptide but a low-molecular-weight synthetic dye and redox-active small molecule. Its IUPAC designation is 3,7-bis(dimethylamino)phenothiazin-5-ium chloride, also referred to by its INN as Methylthioninium Chloride. The compound features a tricyclic phenothiazine core flanked by two dimethylamino groups and carries a formal positive charge stabilized by its chloride counterion. Its molecular formula is C₁₆H₁₈ClN₃S, with a molecular weight of approximately 319.85 g/mol. This distinctive electronic architecture underpins its well-documented capacity to cycle between oxidized (blue) and reduced (leucomethylene blue, colorless) states, a property central to its research utility in electron transport and redox assay systems.

Purity & Analytical Verification (HPLC & MS)

Every batch of Methylene Blue supplied by The Peptide Store is subject to rigorous analytical verification prior to release. High-Performance Liquid Chromatography (HPLC) is employed to confirm compound identity and purity at ≥98%, while Mass Spectrometry (MS) analysis validates molecular weight integrity and confirms the absence of extraneous synthetic byproducts or degradation intermediates. These dual-method verification protocols ensure that each 60-capsule unit delivered to research facilities meets the highest standards of chemical consistency demanded by modern laboratory science.

Quality Control & Lyophilization Integrity

Unlike lyophilized peptide powders, Methylene Blue capsules are manufactured using a controlled dry-fill encapsulation process that preserves compound stability and ensures uniform per-capsule dosing accuracy. Each capsule is filled with precisely 10mg of verified Methylene Blue compound. Batch-level quality control documentation is maintained throughout the production chain, and all capsules are sealed and packaged under conditions designed to minimize moisture exposure and photodegradation, both of which are known to affect the redox integrity of phenothiazine-class compounds.

Safety, Handling & Laboratory Precautions

Methylene Blue is a potent redox-active compound and should be handled exclusively by trained laboratory personnel in accordance with applicable institutional safety protocols. Appropriate personal protective equipment (PPE), including nitrile gloves, laboratory coat, and eye protection, must be worn at all times when handling this material. The compound exhibits strong staining properties and will permanently discolor skin, clothing, and laboratory surfaces. It should be stored away from strong oxidizing agents and direct light sources. All waste disposal must comply with local chemical waste regulations. This product is strictly for in vitro research use and must not be administered to humans or animals under any circumstances.

Reconstitution, Packaging & Storage

Methylene Blue capsules from The Peptide Store are supplied in a sealed, light-resistant container housing 60 capsules per unit. For in vitro research applications, capsule contents may be dissolved in sterile aqueous buffer or appropriate organic solvent systems consistent with the experimental design. Capsules should be stored at room temperature (15–25°C), protected from direct light, and kept in a dry environment. Avoid prolonged exposure to humidity or elevated temperatures, which may compromise compound stability and encapsulation integrity. Do not freeze encapsulated product.

Intended Research Use & Market Positioning

This product is positioned as a premium research-grade tool for scientists investigating mitochondrial electron transport chain dynamics, cellular redox homeostasis, neuroenergetic preservation models, oxidative stress simulations, and metabolic flux analysis in vitro. The encapsulated format offers laboratories a standardized, easy-to-handle alternative to bulk powder, enabling consistent experimental replication across longitudinal study designs. The Peptide Store supplies this compound at a competitive best price, making it accessible to academic institutions, independent research organizations, and contract research facilities seeking reliable, high-purity Methylene Blue for sale.
