Recombinant GDF-8 Lyophilized Peptide Raw Material For In Vitro Laboratory Research Only

• • 1. 1. 1. 1. All operations must be done inside qualified laboratory with complete personal protective equipment. Let raw material reach ambient temperature after taking out from cold storage to avoid moisture condensation.
             2. Weigh sample with analytical balance. Seal container and mark opening date right after sampling, then store under required low temperature.
             3. Dissolve powder with lab-grade purified water or buffer solution following buyer’s own experimental plan by stirring or shaking. No standard formulation is supplied by our company.
             4. Seal leftover solid for cold storage; dispose waste liquid and residues in compliance with local hazardous waste rules.
             Disclaimer: The above steps are only for in vitro laboratory research, no preparation guidance for in vivo application will be provided.

• 1. • • • 1. 1. 1. 1. Unopened vials: Keep tightly sealed. Long-term storage at -20℃ in dry and dark environment with 24 months shelf life; short-term storage at 2~8℃, keep away from direct sunlight, heat, moisture and corrosive chemicals.
                    2. After sampling: Seal the cap immediately, mark opening date and store under low temperature. Minimize repeated opening and freeze-thaw cycles to avoid moisture absorption and protein denaturation.
                    3. Reconstituted solution: Store at 2~8℃ for 3~7 days; aliquot and freeze at -20℃ for long-term preservation.
                    4. Transportation: Keep package sealed, shaded and moisture-proof; cold chain for long-distance shipment, avoid mixing with corrosive goods.
                    Note: The above storage requirements apply only to laboratory research raw material.
