Protein A/G Elution: 10mM Histidine, pH 2.5, is used to elute antibodies from Protein A/G affinity resins under controlled low-pH conditions.

Low-pH Viral Inactivation: Employed as an acidic buffer to inactivate enveloped viruses during downstream bioprocessing of biologics.

Cation-Exchange Chromatography: Utilized for column conditioning, elution, or strip steps where low pH enhances protein interactions with cation exchangers.

Protease Quenching: Applied to rapidly reduce protease activity after digestion reactions by shifting to pH 2.5.

Endotoxin Testing Workflows: Used as a low-endotoxin, sterile diluent/buffer in LAL or endotoxin challenge studies involving Escherichia coli endotoxin.

Acidic Protein Stability Studies: Provides a defined pH 2.5 environment for protein/peptide solubility, aggregation, and stress-testing assays.
