Application
Human and animal cell lines grown in culture are generally stored frozen. Freezing protects the cell line from changes due to genetic drift and minimizes risk of contamination. Liquid nitrogen used in conjunction with a cryoprotective agent such as DMSO is a widely used method for preserving cells. Without the presence of a cryoprotective agent, freezing is lethal to most mammalian cells. Damage is caused by mechanical injury by ice crystals, concentration of electrolytes, pH changes, and denaturation of proteins. These lethal effects are minimized by adding a cryoprotective agent which lowers the freezing point and allows for a slower cooling rate. BPC-tested DMSO also meets the requirements of biotechnology and tissue engineering applications.
Caution
Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.

Application
培养基中生长的人和动物细胞系通常采用冷冻保存。冷冻可以避免细胞系因遗传漂变而发生改变，并且可以最大限度降低被污染的风险。液氮与冷冻保护剂（诸如 DMSO）结合使用，是广泛采用的细胞保存方法。如果不使用冷冻保护剂，大多数哺乳动物细胞都会冷冻致死。冰晶将对细胞产生机械性损伤，此外电解液浓度、pH 值变化以及蛋白质变性，都将对细胞产生损害。冷冻保护剂将降低凝固点并保持更低的冷却速率，可最大限度减小这些致命影响。经生物技术性能认证 (BPC) 测试的 DMSO 还符合生物技术和组织工程应用的要求。
Caution
容易过度冷却，并在室温下缓慢融化固化的产品放在室温下可以再次液化，对其本身无影响。
Features and Benefits
产品经过消毒和过滤，包装在带隔垫的螺纹盖棕色瓶中，可立即使用。符合·USP 和·EP 测试要求
