Cobomarsen
Cobomarsen (MRG-106) is an oligonucleotide inhibitor of miR-155. Cobomarsen inhibits multiple gene pathways associated with cell survival (including JAK/STAT, MAPK/ERK and PI3K/AKT). Cobomarsen can be used for the research of B-cell lymphoma.
For research use only. We do not sell to patients.

Biological Activity
Cobomarsen (10 μM; 48-96 h) reduces cell proliferation and induces apoptosis in U2932, OCI-LY3, and RCK8 cells[2].
Cobomarsen (10 μM; 72 h) significantly increases the expression of the four direct targets in the cell lines that overexpress miR-155[1].
Cobomarsen (10 μM; 12 days) reduces cellular proliferation and induces apoptosis in MF and HTLV-1+ CTCL cells[1].
Cobomarsen (10-50 μM; 7 days) reduces phosphorylation of the downstream signalling proteins AKT, ERK1/2, and STAT-3 in primary human activated T cells or MF cell lines[1].

Solvent & Solubility
H2O : 100 mg/mL (21.11 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.
