The DMSO is stable at room or refrigerated temperatures. Typically, cell freezing media containing serum and DMSO, are stable for at least several days when thawed and refrigerated. Other constituents of freezing medium, primarily serum, may contribute to the appearance of particulates.

General description
Le diméthylsulfoxyde (DMSO) est un solvant aprotique. Les molécules thérapeutiques et toxiques qui ne sont pas solubles dans l'eau sont souvent solubles dans le DMSO. L'association de l'azote liquide et d'un agent cryoprotecteur tel que le DMSO est couramment utilisée pour la conservation des cellules. Le DMSO permet de préparer des solutions mères de diverses molécules et sert également de témoin pour ces molécules. Il est utilisé dans les tests de migration cellulaire pour la dissolution des cellules post-migration. Le DMSO confirmé sans BPC par analyse répond également aux exigences des applications de biotechnologies et de génie tissulaire.

Dimethyl sulfoxide (DMSO) should be a liquid. Why did it arrive as a solid?
1 answer-
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.
