Research Brief
Storing Ara 290: Best Practices
βοΈ Lyophilized Powder Storage
Lyophilized ARA-290 is stable at room temperature during shipping but should be stored long-term at β20Β°C (β4Β°F) or lower where it remains stable for up to 3 years, or at 2β8Β°C (36β46Β°F) for up to 2 years. Protect from light at all times.
π§ͺ Reconstituted Solution
Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2β8Β°C and protected from light. It is stable for up to 6 weeks under these conditions. Do not store in the refrigerator door to avoid temperature fluctuations. Avoid repeated freeze-thaw cycles.
𧴠Handling Precautions
Standard laboratory tolerability practices apply. ARA-290 is for research use only (RUO). Each vial is accompanied by a Certificate of Analysis (COA) detailing purity verification via RP-HPLC and Mass Spectrometry (MS), as well as sterility testing for injectable preparations.
