AAV Affinity Resin Storage: Long-term storage of AAV affinity chromatography resins and prepacked columns in a phosphate buffer (pH 7.0) with 20% ethanol for preservation.

Column Preservation Between Runs: Keeps AAV affinity columns wetted and protected, minimizing microbial contamination and maintaining ligand performance.

System/Column Sanitization Hold: Used as a hold solution to sanitize and store chromatography hardware and flow paths compatible with phosphate/ethanol.

Resin Slurry Preparation and Shipping Buffer: Serves as a stable slurry/transport medium for AAV affinity resins, preventing drying and microbial growth.

Ligand Stability Maintenance: Phosphate buffering at pH 7.0 helps maintain affinity ligand integrity during storage.

Bioburden Control: 20% ethanol inhibits growth of common contaminants such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus during storage.
