General description

Antifoam eliminates excessive foaming formed during impingement, due to proteins and/or carbohydrates in the collection medium. Antifoam B emulsion is a silicone based antifoam. Antifoam B emulsion does not affect the growth of bacteria. Antifoam B emulsion functions as an antifoaming agent in shake flask culture of bacteria.

Application

Antifoam B emulsion has been used:
  • to enhance collection efficiency in collection media
  • as a component in stress granule lysis buffer to reduce foaming, in host cell lysis buffer to reduce foaming caused by detergents
  • to improve solubility of antibiotics
  • as a foaming controls in bacterial growth media
