High Purity Vasoactive Intestinal Peptide VIP Lyophilized Powder Research Grade Biochemical Raw Material

• • All operations for this polypeptide research material must be conducted in a standard laboratory, and comply with conventional safety rules for chemical experiments. Prepare clean lab vessels, dedicated solvents and complete protective gear in advance, and ensure the working space is dry, dust-free and pollution-free.
    
    
    Wear lab coats, disposable gloves and protective goggles throughout the process to prevent direct contact between the powder and skin, respiratory tract and mucous membranes. This protects both operators and the material from external contamination.
    
    
    Carry out weighing and dissolving in a low-humidity environment to prevent the powder from absorbing moisture and altering its physical and chemical properties. Weigh the required quantity accurately with professional measuring tools according to experimental formulas. Slowly add matched laboratory solvent and leave it to stand for a moment for full infiltration of solid particles.
    
    
    After infiltration, swirl or shake the container gently and steadily to promote dissolution. Never shake violently, which may cause liquid splashing, material loss and uneven concentration. Keep mixing until all solids dissolve completely and form a clear, homogeneous solution without visible impurities.
    
    
    After solution preparation, proceed with biochemical tests, molecular research and other basic scientific work following standard procedures. Upon completion of experiments, seal the leftover powder and prepared solution immediately to isolate air, moisture and dust, so as to retain the original stability and purity of the material.
    
    
    This product is solely for academic research and experimental analysis in laboratories. It shall not be used for any non-research purposes, nor applied to human or animal related scenarios.

• 1. • Proper and standardized storage is essential to preserve the molecular structure, purity and inherent physicochemical properties of this polypeptide research material. All storage procedures must comply with laboratory chemical reagent management regulations to prevent performance degradation caused by adverse environmental factors.
       
       
       For unopened, hermetically sealed containers, keep them tightly closed and store at a constant low temperature of -20°C. The storage area should be kept dry, clean and well-ventilated. Keep the product away from strong light, high-temperature heat sources, humid air and corrosive gases. Long-term exposure to harsh environments will damage the internal structure of the material and affect its performance in experiments. Under the recommended sealed and low-temperature conditions, the product remains stable for up to 24 months.
       
       
       After the original package is opened for sampling, expel excess air inside the container and seal it tightly immediately. The opened material still needs to be stored at -20°C with reliable light-proof and moisture-proof protection. To ensure optimal experimental results and material activity, it is strongly recommended to use up all remaining contents within one month after opening.
       
       
       If the solid powder is prepared into a liquid using laboratory solvents, transfer the solution into clean, lightproof containers. Store the liquid reagent in a refrigerated environment of 2–8°C. Avoid drastic temperature changes and repeated freeze-thaw cycles, as these actions will disrupt the composition and stability of the solution. It is recommended to use the prepared solution as soon as possible.
       
       
       For daily storage management, place this material independently on dedicated storage racks. Separate it thoroughly from volatile reagents, oxidizing substances and corrosive chemicals to avoid cross-contamination and accidental chemical reactions. Place the containers stably to prevent collision, falling and vibration. Inspect the sealing status regularly to prevent dust, moisture and other contaminants from entering the container.
       
       
       All of the above storage specifications are formulated exclusively for laboratory research materials. They do not involve any application for humans, animals or clinical scenarios.
