Yes. After dissolving this product in DMSO, the stock solution can be sterilized using a sterile 0.22 µm syringe filter, as long as the filter membrane/housing is compatible with DMSO. This product is soluble in DMSO at 10 mg/mL and insoluble in water. For filtration, use a DMSO-compatible filter, preferably regenerated cellulose (RC) or PTFE; avoid membranes that may leach, swell, or reduce compound recovery.

Is it okay to store the original product and its aliquoted stock solutions not only at -20℃ specifically, but also in some temperature range around -20℃? Can I have certain temperature range for storage?
1 answer-
The acceptable temperature range for products stored at -20°C is -10°C to -25°C. The stability of this product in solution has not been investigated. However, external sources indicate that stock solutions prepared in DMSO are stable for 6 months when stored at -20°C. The same acceptable range would apply.

How long can I store the reconstituted compound in the freezer -20 degrees? i have one that was aliquoted 4 years ago. Is it still ok to use it ?
1 answer-
It is recommended, following reconstitution, to aliquot and freeze -20°C. The stock solutions are stable for up to 6 months at -20°C. The quality of solutions stored frozen for extended periods has not been evaluated. The end user would have to determine suitability. Any color change, cloudiness, or particulate matter present upon thawing would be a visual indicator of degradation.
