Section 7
Regeneration and Storage

Regeneration conditions depend on which type of ligand or protein is used in the
coupling and chromatography process. Refer to textbooks and literature articles
for guidance. In general, 2–4 wash cycles alternating acidic and basic buffers are
useful. Each cycle should consist of a wash of a pH 4.0 buffer (100 mM acetate,
500 mM NaCl) followed by a wash of a pH 8.0 buffer (100 mM phosphate,
500 mM NaCl).

Profinity epoxide resin should be stored dry between 4°C and ambient tempera-
ture. Ligand-coupled Profinity resin should be stored at 4–8°C in an appropriate
buffer that contains a bacteriostat.
