A high concentration of DMSO should never be used for cell culture. 5% is very high and will be dissolving the cell membranes. Most cell lines can tolerate 0.5% DMSO and some cells can tolerate up to 1% without severe cytotoxicity. However, primary cell cultures are far more sensitive.
Why was DMSO banned?
It was also wrongly touted as a cancer cure. In 1965, FDA put the kibosh on much of this activity by banning clinical trials with DMSO because the compound altered the refractive index of eye lenses of laboratory animals. The ban was lifted in 1980 after the intense interest in the substance abated.

Can DMSO explode?
Pure DMSO is stable at low temperature but decomposes around its boiling point of 189 °C. However, the presence of acidic substances can cause it to decompose at significantly lower temperature and potentially result in uncontrollable autocatalytic decomposition of DMSO, leading to runaway scenarios or even explosions.

Why use DMSO instead of water?
From a chemical point of view, echinocandins are more soluble in DMSO, which has a lower dielectric constant than water; this allows them to remain more highly dispersed and accessible to their cellular target (3). This may help account for differences found in MICs between water and this solvent.
