Pharmacological Research MT-1 Afamelanotide Melanotan 1 Powder Complete Inspection Document

• 1. Pre-operation Preparation

  
  
  This product is a dedicated laboratory research reagent. All operations shall be performed by professional researchers in a standard sterile laboratory.
  
  
  Clean the work bench to keep it clean, dry and well ventilated, and remove sundries and residual reagents to avoid cross-contamination. Prepare sterile liquid handling devices, sealed containers, aqueous solvents and protective equipment in advance. All utensils must be cleaned, sterilized and cooled before use.
  
  
  Operators shall wear lab coat, sterile gloves, protective goggles and dust-proof equipment to prevent direct contact of powder and solution with skin, eyes and respiratory tract. Inspect the vial before use to ensure good sealing, and confirm no moisture, caking or discoloration.
  
  

  2. Reconstitution

  
  
  Select suitable solvents such as laboratory-grade sterile water or phosphate buffered saline according to experimental protocols. Add solvent slowly along the inner wall of the vial with sterile tools. Do not impact the powder directly to avoid bubbles and bioactivity loss.
  
  
  Let the vial stand upright for full infiltration, then swirl gently until the powder is fully dissolved into a clear and homogeneous solution. For high-precision cell experiments, filter the solution with a 0.22μm sterile filter.
  
  

  3. Dilution and Experimental Application

  
  
  To prepare working solutions of different concentrations, perform serial dilution with blank solvent. Mix gently after each dilution to ensure even concentration.
  
  
  Draw required volume of solution with sterile tools and transfer it into culture dishes, test tubes and other experimental carriers. Conduct experiments in accordance with specified temperature, reaction duration, pH value and other parameters. Keep complete records for full traceability.
  
  

  4. Post-experiment Handling

  
  
  Tighten and seal the vial immediately after use, then store it under specified conditions. Clean, sterilize and store all used laboratory utensils following standard rules.
  
  
  Collect waste liquid, residual materials and used consumables separately. Dispose of them uniformly in compliance with laboratory hazardous waste regulations. Random dumping is prohibited.
  
  

  5. Additional Notes

  
  
  1. Prepare solutions right before use to maintain optimal bioactivity. Do not store diluted working solutions for a long time.
  2. Opened product has reduced stability. Use it as soon as possible and avoid repeated opening.
  3. Handle the product gently during operation and transportation to prevent package damage and material leakage.
  4. This product is only for in vitro scientific research. Do not alter its intended use, and it shall not be applied to non-research scenarios related to humans and animals.

• 1. 1. General Storage Requirements

     
     
     This lyophilized biological peptide is sensitive to temperature, humidity and light. Store it in a cool, dry, dark and well-ventilated dedicated reagent area.
     
     
     Keep away from heat sources, electrical equipment and direct sunlight. Maintain low humidity to prevent moisture absorption and property changes. Store separately from corrosive and volatile chemicals to avoid cross-contamination.
     
     

     2. Storage for Unopened Products

     
     
     Short-term storage: Keep well-sealed products in refrigerator at 2℃~8℃.

     
     

     Long-term storage: Seal the vial thoroughly and store at -20℃.
     
     
     Place products away from ground moisture. Do not stack heavy items on top to prevent package damage. Follow the first-in, first-out rule. The shelf life is 24 months under standard storage conditions.
     
     

     3. Storage for Opened Products

     
     
     Fully tighten and seal the cap immediately after sampling to minimize exposure to air and moisture.
     
     
     Store opened products at 2℃~8℃ away from light. Avoid repeated opening and moving, and use the product as soon as possible.
     
     

     4. Storage for Reconstituted Solution

     
     
     Liquid solution is much less stable than lyophilized powder. Use it immediately after preparation.
     
     
     For temporary storage, transfer the solution into a clean sealed container and keep it at 2℃~8℃. Complete usage within 24 hours.
     
     
     Do not store at room temperature for a long time or conduct repeated freeze-thaw cycles, which will lead to activity loss and deterioration. Dispose of turbid, precipitated or layered solution in accordance with laboratory hazardous waste regulations.
     
     

     5. Management of Subpackaged Samples

     
     
     Use airtight containers for divided samples. Place them together with desiccant in a light-proof box before refrigeration. Mark each container clearly with product name, subpackaging date and batch number for easy management.
     
     

     6. Daily Maintenance & Notes

     
     
     Check the operation of refrigeration and freezing equipment regularly, as well as package and material status. Isolate damaged, damp, caked or discolored products in a timely manner.
     
     
     Turn on dehumidifiers in humid weather for better moisture protection. Handle products gently during transportation to prevent sealing failure caused by collision.
