Methylene Blue (Research Grade) — Ireland

Methylene Blue (methylthioninium chloride) is a phenothiazine dye and small-molecule compound with a broad range of research applications from mitochondrial biology to neurodegeneration studies. Peptides Lab Ireland supplies pharmaceutical-grade methylene blue for in-vitro research use only.

What Methylene Blue is used for in the lab

Methylene blue is studied for effects on mitochondrial electron transport, cytochrome-c oxidase activity, and its role as an alternative electron carrier in energy metabolism assays. It has been explored in neurodegeneration models (Alzheimer’s, Parkinson’s) for effects on tau aggregation, and in cognitive research for mitochondrial-hormetic pathways. It is also a standard laboratory dye for staining and microscopy.

The HPRA position on Methylene Blue

Methylene blue holds a limited medicinal authorisation in some jurisdictions for specific clinical indications (methemoglobinemia), but the research-grade material we supply is for in-vitro laboratory research use only under the HPRA framework. It isn’t intended for human or veterinary use. Consult a licensed healthcare professional for clinical questions.

What Irish researchers commonly ask about Methylene Blue

Is Methylene Blue legal in Ireland?

Methylene Blue isn’t authorised as a medicine by the HPRA. It’s legal to buy, hold and use as a research chemical for in-vitro laboratory work, and that’s the only use we supply it for. If you want the full regulatory picture, see our Irish researcher’s guide to peptide legality.

What’s in the vial and what does the CoA cover?

Every vial ships with an HPLC purity trace (≥99%), mass-spec identity confirmation, and endotoxin/heavy-metal screening on the batch. The full per-batch Certificate of Analysis is available on request from research@peptideslabuk.com. Our quality system is ISO 9001 certified and third-party testing runs through a UKAS-accredited lab.

How researchers reconstitute Methylene Blue

Standard protocol: let the Methylene Blue vial and your bacteriostatic water come to room temperature, wipe both stoppers with a 70% isopropyl swab, then inject the water slowly down the side wall of the peptide vial. Don’t stream directly onto the powder cake. Swirl gently, don’t shake, and give it five to ten minutes to fully dissolve. Label the vial with compound, concentration and reconstitution date, store at 2–8°C between assays.

How fast does Methylene Blue ship inside Ireland?

same-day shipping on orders placed before 2pm on a working day. Delivery is 24–48 hours to any Irish county via An Post Express or DPD. Cold chain is preserved with insulated wrap plus gel pack. No customs step, no border delays , because it never leaves Ireland.

What’s Methylene Blue typically studied with?

In the Irish research space Methylene Blue tends to appear in neuroprotection, cognitive-pathway and neurotransmission research. It’s often paired with Semax or Selank when researchers are studying combined mechanisms rather than the compound alone.

How should Methylene Blue be stored?

Lyophilised Methylene Blue is stable at ≤-20°C long-term, dessicated. Once reconstituted, keep it refrigerated at 2–8°C and use within the working shelf life described on the CoA. Freeze/thaw cycles degrade peptides, so aliquot the reconstituted solution if you plan to run assays over several weeks.
