Protein Precipitation and Aggregation

Protein precipitation and aggregation are among thee most pervasive issues in downstream processing. They manifest as visible turbidity, increaged subvisible particles, or reduced recovery in chromatography steps. These phenoma arise from physical or chemical stresses that destabilize the nativa protein conformation, leving to hydrophobic interactions, disulfide scrambling, or covalent cross- linking.

Przyczyna i wkład Factors

Common triggers included sharp pH exposure tor chaotropic agents or organic solvents. Incommentate buffer capacity during load or elution steps can cause localized pH shifts that exposure the protein 's stability window. Additionale, high protein concentration, especially near the isoelectric point, promotees selieation d pitation.

Root cause analysis should include testintraf raw materials (e.g., water quality, buffer intrients) o rule out mettatin or endototototinon.
