Affinity Chromatography (His-tagged Proteins): Equilibrates and washes Ni2+/Co2+-charged IMAC resins to remove non-specifically bound proteins prior to elution.

FPLC/Chromatography System Prep: Used to condition and wash affinity columns on FPLC systems before sample loading and between runs.

Magnetic Beads and Spin Columns: Serves as the equilibration and wash buffer for His-tag capture on magnetic beads or spin columns.

Bacterial Lysate Clarifications: Optimizes wash steps during purification from Escherichia coli and other microbial expression systems to reduce contaminants.

Low-Endotoxin Workflows: Suitable for endotoxin-sensitive applications, helping maintain low endotoxin burden in downstream cell-based assays.

Nuclease-Sensitive Applications: DNase/RNase-tested and sterile buffer supports workflows involving nucleic acids or nucleic acid–binding proteins without introducing nucleases.

Sample Preparation for Downstream Analyses: Provides consistent conditions prior to elution for proteomics, enzymatic assays, and structural studies.

General Affinity Resin Maintenance: Used for routine column equilibration and intermediate washing to enhance reproducibility and resin longevity.
