What is the molarity of DMSO?
DMSO will have a molarity of 14.1M, based on a density of 1.1 g/mL and a molecular weight of 78.13 g/mol.
What is the DMSO dissolved in?
DMSO is not dissolved in any solvent. It is a pure chemical compound that is a liquid at room temperature.
Where does DMSO come from?
DMSO is known to have been isolated from tree bark in the past. It is now a commericially synthesized solvent.
What concentration of DMSO do I use in a cell freezing media?
DMSO is usually used at 1-10%, depending on the cell line. For the cell freezing media that we offer, it is used at 8.7% concentration.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
What is the specification for 'pass' for cell freezing on the Certificate of Analysis for Dimethyl sulfoxide (DMSO)?
Product D2438 is assessed for cell freezing. Cells are frozen and stored at -70°C. The cells are thawed, cultured and viability is assessed at 24 hours. There is no evidence of cytotoxicity or abnormal cell growth.
Dimethyl sulfoxide (DMSO) should be a liquid. Why did it arrive as a solid?
DMSO supercools easily, and re-melts slowly at room temperature. The melting point is 16-19 °C. The solidified product can be re-liquefied by warming to room temperature without detriment to the product.
What is the basis for the endotoxin specification for Dimethyl sulfoxide (DMSO)?
The industry standard for 'endotoxin free' is less than 1 EU/mL.
What is the difference between Dimethyl sulfoxide (DMSO) Products. D1435 and D2438?
Products D1435 and D2438 both meet the USP specifications. The D2438 is sterile-filtered, but D1435 is not. Furthermore, the D2438 is quality control tested for endotoxin and use-tested for cell freezing.
What type of filter is used to sterile-filter Dimethyl sulfoxide (DMSO)?
DMSO can be sterile-filtered through a 0.2 micron PTFE filter. The sterility testing is per the current US Pharmacopoeia method.
