Casimersen (SRP-4045) is an antisense oligonucleotide of the phosphorodiamidate morpholino oligomer class that binds to exon 45 of dystrophin pre-mRNA, restores the open-reading frame through exon 45 skipping. Casimersen enables the production of an internally truncated yet functional dystrophin protein, thereby serving as a specialized molecular tool for studying exon-skipping mechanisms and therapeutic development in Duchenne muscular dystrophy research.

Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
