Casimersen
Based on 1 Customer Validation
Casimersen (SRP-4045) is an antisense oligonucleotide of the phosphorodiamidate morpholino oligomer subclass. Casimersen binds to exon 45 of dystrophin pre-mRNA, restores the open-reading frame (by skipping exon 45) resulting in the production of an internally truncated but functional dystrophin protein. Casimersen can be used for the research of Duchenne muscular dystrophy (DMD).
For research use only. We do not sell to patients.

Solvent & Solubility
H2O : 100 mg/mL (13.19 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
