General description

Antifoam SE-15 is a silicone-based product used to prevent or minimize foaming in both microbial fermentation systems and mammalian suspension cultures. Control of foaming minimizes damage to the cells, resulting in increased protein/antibody production.

Application

Antifoam SE-15 has been used:

  • in the preparation of ramified rolling circle amplification (RAM) amplification buffer.
  • to find its effects on cell viability, virus infectivity and PCR (polymerase chain reaction) performance.
  • as a constituent of phosphate-buffered saline (PBS) for the determination of total antioxidant status (TAOS) by 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assay.
  • as a component of autoinduction expression culture.
  • as a component of cyclic adenosine monophosphate (cAMP) detection buffer.

Features and Benefits

  • Controls foaming in microbial culture flasks or fermentations
  • Non-toxic to the culture medium
  • Can be pumped to fermenter on an as-needed basis

Components

Antifoam SE-15 is an aqueous emulsion containing 10% active silicon and non-ionic emulsifiers .

Preparation Note

Antifoam SE-15 can be pre-diluted with 3-10 parts of cool water to aid in dispersion. Pre-diluted
suspensions should be used immediately.
