MT2 Starter Research Kit Reconstitution: Step-by-Step Guide
The MT2 30mg Starter Research Kit contains three Melanotan 2 vials (10mg each, 30mg total) supplied with sterile water included in the kit. This starter kit format provides everything needed for MC1R and MC4R melanocortin receptor pharmacology research from a single package. Each 10mg MT-2 vial is reconstituted individually using the included sterile water supply.
Kit Contents
- 3× Melanotan 2 10mg lyophilised vials
- Sterile water for injection (included in kit)
- Sterile syringes (if included) or source separately
- Alcohol swabs (70% isopropyl)
- Nitrile gloves
- Permanent marker for labelling
Important Note on Sterile Water vs BAC Water
The starter kit includes sterile water rather than bacteriostatic water. Sterile water lacks the benzyl alcohol preservative of BAC water, which means reconstituted MT-2 vials should be used within a shorter timeframe — ideally within 5–7 days when stored at 2–8°C. For extended storage beyond one week, reconstitute with BAC water (purchased separately) to benefit from the 28-day refrigerated stability window. The kit's sterile water is suitable for single-experiment or short-run research protocols.
Step-by-Step Reconstitution Protocol (Per Vial)
Step 1 — Prepare workspace. Clean work surface with 70% isopropyl alcohol. Allow to dry. Wear nitrile gloves throughout.
Step 2 — Swab vial stoppers. Clean the rubber stopper of the MT-2 vial and the sterile water vial with separate fresh alcohol swabs. Air dry 10 seconds each.
Step 3 — Draw 2mL of sterile water. Using a sterile syringe, draw 2mL of sterile water from the kit's water supply.
Step 4 — Inject slowly along the vial wall. Direct the sterile water slowly down the inner glass wall of the MT-2 vial over 15 seconds. Do not inject directly onto the lyophilised powder.
Step 5 — Dissolve gently. Swirl gently for 20–30 seconds. MT-2 dissolves readily — the solution should be clear and colourless quickly. Protect from light after dissolution. Do not shake or vortex.
Step 6 — Label. Record reconstitution date, concentration (5mg/mL), and initials. Note the 5–7 day expiry when using sterile water.
Resulting Concentration Per Vial
Adding 2mL sterile water to each 10mg MT-2 vial yields a stock concentration of 5mg/mL (5000mcg/mL). For MC1R and MC4R receptor pharmacology assays, working concentrations of 0.1nM–1µM are prepared by serial dilution.
Concentration Reference Table
| Sterile Water Added | Resulting Concentration | Shelf Life |
|---|---|---|
| 2mL (sterile water) | 5.0mg/mL | 5–7 days at 2–8°C |
| 2mL (BAC water) | 5.0mg/mL | 28 days at 2–8°C |
Storage and Kit Management
Store unreconstituted MT-2 vials at −20°C, protected from light. Reconstitute one vial at a time as needed for research protocols — the remaining unreconstituted vials remain stable in the freezer. Once a vial is reconstituted with the kit's sterile water, store at 2–8°C and use within 5–7 days. Wrap vials in foil or store in a light-protected container as MT-2 is sensitive to UV exposure. For longer-term reconstituted storage, use BAC water purchased separately.
Troubleshooting Common Reconstitution Issues
Powder not dissolving: Gently tilt and swirl to bring undissolved powder into contact with solvent. Do not heat. If incomplete after 60 seconds, inspect for moisture ingress or compromised seal.
Cloudy solution: Cloudiness may indicate aggregation or contamination. Discard if cloudiness persists after gentle swirling.
Foaming: Allow to settle naturally. Reduce injection speed on subsequent attempts and ensure stream is directed along the glass wall.
Loss of material: Swirl to contact all inner surfaces. Invert and draw from the stopper end for maximum recovery.
Research Application Notes
The starter kit format is designed for researchers beginning MC1R and MC4R pharmacology research who require multiple vials for concentration-response studies across different cell model systems. Each of the three 10mg vials can be reconstituted for separate experimental runs, ensuring fresh compound for each assay series. For B16F10 melanoma melanogenesis assays (MC1R) and GT1-7 hypothalamic cell model studies (MC4R), the 5mg/mL stock from each vial provides sufficient material for extensive dilution series. MT2 30mg Starter Research Kit is available from Pinnacle Peptides, with each vial verified at ≥99% purity by HPLC and mass spectrometry.
