Protein stability test
WebbProtein-based alcohol-resistant foam concentrates should be subjected to a stability test with acetone. A foam solution should be prepared at the approved concentration and gently applied to the surface of a tray containing acetone. Webb30 jan. 2024 · The first thing to do is to determine at which pH you need to work. For example, if you’re planning an ion exchange purification you need to choose the right pH to have your protein charged as you want. Indeed, when the pH buffer is equal to the pI (isoelectric point), the protein has no charge. Consequently, the protein is not able to …
