As an accredited β-Galactosidase factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | White plastic bottle with blue labeling, screw cap, contains 1g β-Galactosidase lyophilized enzyme, stored refrigerated, tamper-evident seal. |
| Storage | β-Galactosidase should be stored at -20°C to maintain its stability and activity. The enzyme is typically supplied as a lyophilized powder or aqueous solution, and should be kept tightly sealed, protected from light and moisture. For long-term storage, aliquoting is recommended to avoid repeated freeze-thaw cycles, which can reduce enzyme activity. Always follow manufacturer guidelines for optimal storage conditions. |
| Shipping | β-Galactosidase is shipped in insulated packaging with ice packs or dry ice to maintain its stability and activity during transit. The shipment is marked as temperature-sensitive and may require expedited delivery. Containers are sealed and labeled according to safety regulations to ensure safe handling and compliance with chemical transport guidelines. |
