Buffers & maintenance
Binding buffer20 mM sodium phosphate, 150 mM NaCl, pH 7.0
Elution buffer0.1 M glycine-HCl pH 3.0
Storage buffer20% ethanol
CIPClean with 6 M guanidine-HCl or 0.1 M acetic acid, then re-equilibrate in binding buffer. Native Protein A is alkali-labile: keep NaOH at or below 20 mM and expect capacity to fall and ligand leakage to rise with repeated caustic exposure.
