Storage & Handling

Lyophilized (unopened): Store at ≤ −20 °C, protected from light and moisture. For long-term archival, ≤ −80 °C is recommended.
After reconstitution: Prepare sterile aliquots; store at ≤ −80 °C for maximal stability (≤ −20 °C for short-term work). Avoid repeated freeze–thaw cycles.
Handling notes: Let vials equilibrate to room temperature before opening to minimize condensation. Use sterile water or compatible buffer (e.g., PBS). Do not expose to extreme pH or oxidants.
Research Use Only (RUO): Not for human or veterinary use, ingestion, diagnostic, or therapeutic applications.
