LR3 Insuli-Like Growth Factor-1 High Purity Recombinant Peptide Lyophilized Raw Material for Research

• 1. Pre-operation Preparation

  
  
  This product is a dedicated laboratory research reagent. All operations must be performed by professional staff in a standard sterile laboratory.
  
  
  1. Environment preparation: Clean the work bench to keep it tidy, dry and well ventilated. Remove sundries and residual reagents to avoid cross-contamination.
  2. Tool preparation: Prepare sterile liquid handling devices, sealed containers, dedicated aqueous solvents and cleaning wipes. All utensils shall be cleaned, sterilized and cooled to meet sterile standards.
  3. Personal protection: Wear lab coat, sterile gloves, protective goggles and dust-proof equipment properly to prevent direct contact of powder and solution with skin, eyes and respiratory tract.
  4. Product inspection: Check the vial before use. Ensure the package is well sealed, and the material has no caking, discoloration or moisture.
  
  

  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, as excessive bubbles may affect bioactivity.
  
  
  After adding solvent, place the vial upright for full infiltration. Swirl the vial gently until the powder is completely dissolved and the solution becomes clear and homogeneous. For rigorous cell experiments, filter the solution with a 0.22μm sterile filter.
  
  

  3. Dilution and Experimental Application

  
  
  To prepare working solutions of different concentrations, dilute the stock solution step by step 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 detailed records to track the whole usage process.
  
  

  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 uniformly, and dispose of them in compliance with laboratory hazardous waste regulations.
  
  

  5. Additional Guidelines

  
  
  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 to prevent package damage and material leakage.
  4. This product is only for in vitro scientific research and shall not be used for other purposes.

• 1. 1. General Storage Requirements

     
     
     This lyophilized biological research material is sensitive to temperature, humidity and light. Please 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 ambient humidity to prevent the powder from absorbing moisture and caking. Store separately from corrosive and volatile chemicals to avoid contamination.
     
     

     2. Storage for Unopened Products

     
     
     Short-term storage: Keep well-sealed products in refrigeration at 2℃–8℃.

     
     

     Long-term storage: Seal the vial tightly and store at -20℃.
     
     
     Arrange products neatly, keep away from ground moisture and do not place 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 recommended conditions.
     
     

     3. Storage for Opened Products

     
     
     Tighten the cap completely right after sampling to minimize exposure to air and reduce risks of oxidation and moisture absorption.
     
     
     Store opened products at 2℃–8℃ away from light. Avoid frequent moving and repeated opening. Use the material as soon as possible to retain its activity.
     
     

     4. Storage for Reconstituted Solution

     
     
     The 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℃ in dark place. Finish use within 24 hours.
     
     
     Do not store at room temperature or perform repeated freeze-thaw cycles, which will lead to activity loss and deterioration. Dispose of abnormal solution with turbidity or sediment in accordance with laboratory waste regulations.
     
     

     5. Subpackaged Samples & Daily Management

     
     
     Use fully sealed containers for divided samples. Place them together with desiccant in a light-proof box before putting into refrigeration. Mark each container with product name, subpackaging date and batch number for easy management.
     
     
     Check the operation of storage devices, package integrity and material status regularly. Isolate products with damage, moisture or discoloration in a timely manner. Turn on dehumidification equipment in humid weather. Handle products gently during transportation.
