Research Grade Selank Peptide Powder, High Purity Biochemical Material, Reagent for In Vitro Laboratory Research

1. Product Overview

• 1. Pre-operation Preparation

  
  
  This product is exclusively for in vitro scientific research and shall be handled only by professional researchers. Clean the working area in advance and keep it clean, dry and well ventilated to prevent 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 avoid direct contact of powder and solution with skin, eyes and respiratory tract. Check the package before use to ensure good sealing and normal material condition.
  
  

  2. Powder Dissolution

  
  
  Use purified water or buffer solution according to experimental protocols. Add solvent slowly into the container, then add the sample and stir or swirl gently until fully dissolved. For high-precision experiments, filter the solution with sterile membrane to remove fine impurities.
  
  

  3. Dilution and Application

  
  
  To prepare solutions of different concentrations, perform serial dilution with blank solvent and mix thoroughly after each step. Add appropriate amount of solution into reaction vessels, cell culture systems and other carriers. Conduct experiments strictly in accordance with preset parameters and record all data completely.
  
  

  4. Post-operation Handling

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

  5. Notes

  
  
  1. Aqueous solution has poor 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 moisture deterioration.
  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 separate area, away from heat sources, strong light and electrical devices. Keep it apart from corrosive and volatile chemicals to avoid cross-contamination and deterioration.
     
     

     2. Storage for Unopened Products

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

     
     

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

     
     

     Keep products away from ground moisture. Do not place heavy items on the packages to prevent 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 immediately after use to block air and moisture. Store at 2℃~8℃ in dry and dark conditions. Avoid frequent opening and use the product as soon as possible.
     
     

     4. Storage for Prepared Solution

     
     
     The solution is much less stable than solid powder. Prepare and use it right away. For temporary storage, transfer to a clean sealed container and refrigerate 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. Discontinue use and dispose of the solution properly if turbidity or precipitate appears.
     
     

     5. Management of Divided Samples

     
     
     Store divided samples in airtight containers with desiccant in dark places. Mark product name, subpackaging date and batch number on containers for management and traceability.
     
     

     6. Daily Notes

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