neoFroxx® Dimethyl sulfoxide (DMSO) for cell biology, 500 ml

For more undemanding cells/serum-containing applications/self-makers:
DMSO to prevent ice crystal formation during the freezing process. Due to its cell toxicity, DMSO should only ever come into contact with cells in already cooled medium. Serum as an additive in the cryomedium increases the survival rate of the cells.
