| Store at 4°C. |
| A nonionic detergent (0.1% Triton X-100 or 2% β-octyl glucoside) may be included in the wash buffer to reduce nonspecific
hydrophobic interactions.

| If the target protein contains cysteines and is an intracellular protein, reducing agents such as 1 mm DTT should be included in the wash buffer. DTT (1 m) stock solutions should be made fresh or stored as aliquots at −20°C and thawed immediately before use.
