Methylene blue (methylthioninium chloride) is a heterocyclic aromatic phenothiazine compound and a classic redox-active dye. It is a small molecule — not a peptide — supplied in capsule form as a reference material for laboratory use.
Research context
In published literature, methylene blue is studied in the context of mitochondrial electron-transport, redox-cycling, and cellular-bioenergetics research using in-vitro and preclinical models. Glow Peptides supplies Methylene Blue strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
Methylene Blue is supplied in capsule form as a research reference material. General laboratory handling practice for encapsulated materials of this type:
- Storage: keep capsules sealed in a cool, dry place away from light and humidity; refrigeration extends shelf life.
- Handled as supplied: encapsulated reference materials involve no solvent or preparation step.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Check the lot documents shown for the selected material and match the report lot number to your label. Documentation may be missing or held for clarification. A document on file does not itself establish independent analytical review, identity, purity, or sterility.
