一般描述
消泡剂A是一种有机硅类产品，可用于防止或减少微生物发酵系统和哺乳动物悬浮培养物中的发泡现象。 控制发泡可以最大限度地减少细胞损伤，从而提高蛋白质/抗体产量。对水性和非水性体系极为有效。在1-50ppm浓度范围内有效。
应用
消泡剂A浓缩液可用于：
- 生物反应器培养以生产葡萄球菌肠毒素C（SEC）。
- 防止污泥好氧处理时产生泡沫。
- 研究表面张力对鼓泡过程中生物气溶胶生成的影响。
特点和优势
- 分子生物学级，经过测试可用于细菌发酵。
- 非常有效的水系和非水系消泡剂。
- 由 100% 活性有机硅聚合物制成，不含乳化剂。
- 通常在 1-100 ppm范围内有效。
- 产品在 pH 5 到 9范围内稳定。
- 可以直接添加到发酵培养基中，但是不推荐根据需要将其泵入发酵罐中。
组分
消泡剂A是一种不含非离子型乳化剂的100％活性有机硅聚合物。
制备说明
消泡剂A可通过采用3-10倍的丙二醇水溶液或非水植物油通过缓慢混合而进行预稀释。

Substantial evidence indicates that molecules released by infectious organisms affect virulence and influence immunity to infection. The characterization of extracellular molecules and their mechanism of release is therefore critical to understanding host-parasite relationships. The cestode parasite Mesocestoides corti is known
