• 1. Pre-operation Preparation

  
  
  This product is an in vitro laboratory research reagent and shall only be handled by professional researchers. Clean the working area in advance and keep it clean, dry and well ventilated to avoid cross-contamination. Prepare experimental containers, liquid handling tools, solvents and protective equipment. All utensils must be cleaned, sterilized and cooled before use.
  
  
  Wear lab coat, gloves and goggles during operation to prevent direct contact of powder and solution with skin, eyes and respiratory tract. Inspect the package before use to ensure intact sealing and normal material condition.
  
  

  2. Powder Dissolution

  
  
  Use purified water, dilute acetic acid or buffer solution as solvent in accordance with experimental protocols. Add solvent slowly into the container, then put in the sample and stir or swirl gently until fully dissolved. Filter the solution with sterile membrane to remove impurities for high-precision experiments.
  
  

  3. Dilution and Experimental Application

  
  
  To prepare working solutions of different concentrations, perform serial dilution with blank solvent and mix thoroughly after each step to ensure uniform concentration.
  
  
  Pipette appropriate amount of solution and add it into reaction vessels, cell culture systems and other experimental carriers. Conduct experiments strictly in accordance with preset temperature, reaction time, pH value and other parameters, and keep complete records.
  
  

  4. Post-operation Handling

  
  
  Seal the original vial tightly immediately after experiments and store as required. Clean, sterilize and store all used utensils following standard laboratory procedures.
  
  
  Collect waste liquid, residual materials and used consumables separately. Dispose of them in compliance with waste management regulations. Random dumping is prohibited.
  
  

  5. Additional Notes

  
  
  1. Aqueous solution has limited stability. Prepare and use it immediately to prevent component degradation.
  2. The product is highly hygroscopic and light-sensitive. Use it up promptly after opening and avoid repeated opening.
  3. Handle gently during operation and transportation to prevent package damage, leakage and deterioration caused by moisture.
  4. This product is only for in vitro scientific research. Do not alter its intended use.

• 1. 1. General Storage Requirements

     
     
     This lyophilized peptide powder is highly hygroscopic and sensitive to temperature and light. Store it in a cool, dry, dark and well-ventilated dedicated area. Keep away from heat sources, strong light and electrical equipment. Store separately from corrosive and volatile chemicals to avoid cross-contamination and deterioration.
     
     

     2. Storage for Unopened Products

     
     
     Short-term storage: Keep the package fully sealed and refrigerate at 2℃~8℃.

     
     

     Long-term storage: Seal tightly and store at -20℃ away from light.

     
     

     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 of unopened products is 24 months under standard conditions.
     
     

     3. Storage for Opened Products

     
     
     Reseal the package completely right after each use to isolate air and moisture. Keep opened products at 2℃~8℃ in dry and dark conditions. Minimize repeated opening and use the material as soon as possible.
     
     

     4. Storage for Prepared Solution

     
     
     Liquid solution is much less stable than solid powder. Use it immediately after preparation.

     
     

     For temporary storage, transfer the solution into a clean sealed container and keep it refrigerated at 2℃~8℃ for no more than 24 hours.

     
     

     Do not store at room temperature for a long time or perform repeated freeze-thaw cycles, which will cause component degradation and property changes. Discontinue use and dispose of the solution properly if turbidity or precipitation occurs.
     
     

     5. Management of Subpackaged Samples

     
     
     Use airtight containers for divided samples and store together with desiccant in dark places. Mark product name, subpackaging date and batch number clearly for management and traceability.
     
     

     6. Daily Maintenance & Notes

     
     
     Check storage equipment, packages and material status regularly. Isolate damaged, damp, caked or discolored materials in a timely manner. Use dehumidifiers in humid conditions. Handle products gently during transportation to prevent seal damage caused by impact.
