Application
Antifoam A has been used in a study to determine ultra trace arsenic species in water samples by hydride generation atomic absorption spectrometry after cloud point extraction. Antifoam A has also been used in a study to demonstrate a simple method to increase the amount of protein in a culture and to provide insight into how antifoams interact with microbial cell factories.

The establishment of an efficient and reliable protein-purification pipeline is essential for the success of structural genomic projects. The SSGCID Protein Purification Group at the University of Washington (UW-PPG) has established a robust protein-purification pipeline designed to purify 400 proteins

Pichia pastoris is a widely-used host for recombinant protein production. Initial screening for both suitable clones and optimum culture conditions is typically carried out in multi-well plates. This is followed by up-scaling either to shake-flasks or continuously stirred tank bioreactors.
