HG 191AA Somatropi High Purity Peptide Raw Material for Laboratory Research

• As a professional biological scientific research reagent, all operations must be completed in a compliant and sterile professional laboratory by personnel with certified biological experiment operation qualifications, in strict accordance with biosafety experiment guidelines.

  Before operation, tidy up the sterile operating platform to ensure a clean, dry, ventilated and pollution-free working environment. Prepare sterilized pipetting equipment, sealed reagent bottles, constant-temperature experimental devices, special solvents and other appliances in advance. All tools must be sterilized at high temperature, dried and cooled to eliminate exogenous contamination. Operators shall wear complete professional protective equipment, including laboratory protective clothing, sterile gloves, dust masks and goggles, to avoid direct contact of powder and prepared solution with skin, eyes and respiratory mucosa.

  With a lyophilized powder structure and excellent solubility, the product can be reconstituted and prepared with qualified sterile laboratory solvents according to specific experimental schemes. It is recommended to add the solvent slowly in portions and assist dissolution with gentle shaking or low-speed constant-temperature stirring to avoid insufficient dissolution and local aggregation caused by one-time excessive solvent addition. Subsequent biochemical experiments, cell experiments and mechanism research operations can be carried out after the powder is completely dissolved and the solution becomes clear and transparent.

  All prepared solutions are recommended to be prepared and used immediately to maximize the retention of biological activity and avoid activity attenuation, solution deterioration and bacterial growth caused by long-term standing. After the experiment, seal and store the remaining raw materials in a timely manner. Experimental waste liquid and residue shall be classified and disposed of uniformly in accordance with laboratory biological waste disposal specifications, and random dumping and discarding are strictly prohibited.

• 1. The biological activity and physical and chemical state of this product are sensitive to temperature, humidity and light conditions of the storage environment. Standardized storage methods can effectively maintain stable product quality and extend the effective service life. The specific storage requirements are as follows:

     Unopened finished products can be stored in a dark, dry environment at 2℃-8℃ for short-term routine preservation, kept away from high-temperature heat sources, strong light, humid air and corrosive gases with intact and sealed packaging to prevent moisture absorption, oxidation and activity attenuation. For long-term storage, the product needs to be hermetically sealed and stored in a low-temperature freezing environment of -20℃ with enhanced moisture-proof, light-proof and oxygen-isolation protection to slow down material aging and deterioration.

     For opened materials, seal the packaging tightly immediately after each operation to minimize exposure time in the air and prevent invasion of water vapor and impurities. Opened materials for short-term use shall be fixed in a low-temperature and dark area without frequent movement and drastic temperature changes. Reconstituted solutions have weak stability and cannot be stored at room temperature for a long time. Temporary storage requires sealed and dark preservation at 2℃-8℃, and the solutions shall be used up as soon as possible.

     Establish a regular inspection mechanism for daily warehouse management, regularly check packaging tightness, material appearance and environmental temperature and humidity, and clean up dust and sundries in the storage area to keep the environment clean and dry. Follow the first-in-first-out principle to reasonably arrange material usage and avoid long-term overstock and failure. Strengthen moisture-proof and temperature-control measures in humid and high-temperature seasons to ensure stable material storage.
