MTII, Melanotan2

Description

Melanotan II, commonly written MT-II or MTII, is a synthetic cyclic analogue of alpha-melanocyte stimulating hormone and one of the most frequently requested melanocortin reagents among research peptides Canada buyers working in pigmentation biology. It is supplied here as a lyophilized 10 mg vial for reconstitution in the laboratory, for in-vitro investigation only. This page is for qualified research purchasers evaluating supply for benchwork — not for personal use of any kind.

Overview

Each unit is a single sealed vial containing 10 mg of MT-II as a white lyophilized powder, ready to be reconstituted in a solvent appropriate to the assay being run. Lyophilization is the reason the material can be shipped and stored as a stable solid rather than a solution: the peptide sits dry until the researcher decides the concentration and buffer, which keeps the reagent flexible across different protocols and avoids the freeze-thaw and hydrolysis problems that come with pre-dissolved product. The vial is available singly or as a box of ten for labs running extended studies or working across several concurrent projects, so a research group can hold a matched supply from the same production run rather than assembling work from mixed batches. Orders ship cold and discreetly from within Canada with tracking, avoiding cross-border customs handling and the temperature exposure that comes with it.

What it is known for

Within the melanocortin family, MT-II is the reference-point reagent — the broad-spectrum analogue researchers reach for when studying melanocortin receptor activity generally, rather than the more receptor-selective analogues used for narrower questions. That familiarity is much of why it is chosen: protocols, published methodology and comparison data around it are extensive, so a lab has a well-established point of reference. On the supply side, buyers choose this listing for the independent verification. Purity by HPLC and identity by mass spectrometry are run by Janoshik, a third-party analytical laboratory, and the certificate of analysis is matched to the batch in the vial rather than being a generic document reused across production runs.

Key features

• Lyophilized 10 mg presentation — The peptide arrives as a dry solid, so you control the solvent and final concentration to suit your protocol instead of inheriting someone else’s formulation.
• Third-party HPLC purity testing — Purity is verified by an outside analytical lab rather than self-reported, so an unexpected assay result is less likely to trace back to unknown material in the vial.
• Mass spectrometry identity confirmation — Confirms the molecule in the vial is the peptide named on the label — the check that separates a verified reagent from a powder you have to trust on faith.
• Batch-matched certificate of analysis — The COA corresponds to the specific lot you receive, which is what documentation-conscious labs and institutional purchasing need for records and reproducibility.
• Cold storage and cold-chain dispatch — Peptides degrade with heat and moisture exposure; handling the material cold from storage through shipping protects the purity you paid to have verified.
• Domestic Canadian fulfillment with tracking — No customs delay or unmonitored border warehousing, and a traceable transit window you can plan experiments around.
• Single vial or box of ten — Take a single unit for method development and pilot work, or a ten-vial box when you need consistent material across a longer study.
• Discreet packaging — Deliveries to shared institutional mailrooms or lab reception arrive without describing their contents on the outside.

Benefits

• You can attribute experimental variance to your variables rather than to reagent quality, because purity and identity are independently documented.
• Reconstitution stays under your control, so the reagent fits your buffer system and concentration range instead of the other way around.
• Shorter, temperature-managed domestic transit means less risk of material arriving compromised.
• Ten-vial ordering lets a study run on consistent material from a single verified batch.
• Documentation is ready for lab records, method write-ups and internal procurement review without chasing the supplier for paperwork after the fact.

Specifications

Typical applications

• In-vitro study of melanocortin receptor binding and signalling
• Pigmentation and melanogenesis research at the cell-culture level
• Reference or comparator compound alongside more receptor-selective melanocortin analogues
• Assay development and method validation work requiring a well-characterized melanocortin peptide
• Analytical work such as HPLC or MS method calibration against a verified reagent

Important information

• Research use only. This product is not a drug, supplement, food or cosmetic. It is not intended to diagnose, treat, cure or prevent any disease and is not for human or veterinary use, ingestion or administration.
• Keep the vial cold and sealed until you are ready to reconstitute; the lyophilized state is what preserves it.
• Choose a reconstitution solvent appropriate to your assay and prepare the solution under conditions suited to peptide handling.
• Once reconstituted, treat the solution as a working reagent — plan aliquoting to limit repeated freeze-thaw cycles.
• Request or download the batch-matched certificate of analysis and file it against your lot number before beginning work.
• Purchasing is intended for qualified research buyers and laboratory settings.

Common questions

What exactly arrives in the vial?

A 10 mg lyophilized (freeze-dried) powder in a sealed vial. It contains no solvent — you reconstitute it in the laboratory with a solvent appropriate to your protocol.

Who performs the testing?

Janoshik, an independent third-party analytical laboratory. They run HPLC for purity and mass spectrometry for identity confirmation.

Is the certificate of analysis specific to my batch?

Yes. The COA is matched to the production batch the vial came from, not a generic document reused across runs.

Why order the box of ten rather than single vials?

So a longer study runs on material from consistent, verified stock. Reordering repeatedly can mean working across different batches, which introduces a variable you would rather not have in a multi-month project.

How is it shipped, and does it cross the border?

It ships from within Canada, cold and discreetly packaged, with nationwide tracking. Domestic dispatch avoids customs handling and the unpredictable temperature exposure that comes with it.

Can I buy this for personal use?

No. This is a laboratory research reagent supplied for in-vitro use only. It is not for human or veterinary use in any form.

In summary

MT-II is the general-purpose melanocortin analogue most pigmentation research is built around, and this listing supplies it the way a lab wants it: 10 mg lyophilized, independently verified for purity and identity, with batch-matched paperwork and cold, tracked domestic delivery. Order the single vial to develop your method, or the box of ten to keep an extended study on one consistent batch.
