Long Arg3 IGF-1 Freeze Dried Powder Professional Lab Research Material

• • 1. 1. Precondition

          All operations are restricted to in-vitro laboratory preparation for research only. Prepared solution shall not be applied on human bodies in any form.

          Required Auxiliary Materials

          Sterile lab buffer solution such as PBS or lab-grade purified water, purchased separately as common lab consumables.

          Dissolving Procedures

          1. Preparation: Perform all operations inside sterile laminar flow cabinet. Sterilize all tools in advance under room temperature away from strong light.
          2. Solvent addition: Measure required sterile buffer and add gently along inner bottle wall based on target experimental concentration. Avoid direct flushing toward lyophilized powder.
          3. Standing dissolution: Seal bottle cap after solvent feeding, leave still for 30~60 minutes at room temperature for natural dissolution. Rotate bottle mildly if tiny undissolved residue exists, no violent shaking.
          4. Aliquot & preservation: Split homogeneous stock solution into sterile tubes by single-test dosage.
             
             
             Short-term reserved aliquot: Store at 2~8℃ and consume within 7 days;
             
             
             Long-term reserved aliquot: Seal and store at -20℃ away from light, prevent repeated freeze-thaw cycles.

          Application in Experiment

          Dilute finished stock solution following self-made lab experimental formula and pipette quantitative dosage into cell culture medium for in-vitro cell incubation and related mechanism research.

          Precautions

          1. Operations must be finished by qualified lab researchers inside certified laboratory space. Prepared liquid is only available for in-vitro cell and biochemical research tests.
          2. Unused original lyophilized powder shall be stored at -20℃~-80℃ in sealed and dark environment.
          3. The prepared liquid is forbidden for food processing, cosmetic manufacturing or other non-research usage.

          Disclaimer

          This preparation guide is only for in-vitro academic laboratory reference, supplier takes no responsibility for any improper non-research usage.

• 1. • • • 1. Unopened original lyophilized powder

           • Long term storage: Keep sealed vials away from light and moisture at -20℃ ~ -80℃ to maintain original bioactivity; stay away from high temperature and direct sunlight.
           • Temporary short storage: Can be kept at 2~8℃ for a short period only; ambient long-time storage is prohibited to prevent activity degradation.
           • Storage condition: Dry, dark warehouse, separate from volatile chemical reagents.

           2. Reconstituted experimental solution

           • Short-term preservation: Store aliquoted solution at 2~8℃, finish consumption within 7 days.
           • Long-term preservation: Seal sub-packed liquid and store at -20℃ in dark place; repeated freeze and thaw must be avoided to prevent polypeptide denaturation.

           3. Partially used leftover powder after opening

           Seal the bottle tightly immediately after sampling, wrap with sealing film and return to low-temperature storage space to reduce moisture and air infiltration.

           4. Warehouse Reminder

           This item is lab research raw material only, keep separate from food and cosmetic raw materials during storage. Cold chain is recommended for transit temporary storage; transfer to specified low-temperature condition once goods arrive.
