WebQ How do I best evaluate the efficiency of column regeneration (the restoring of column binding capacity)? A We recommend to do a dynamic binding capacity test (e.g., at 10% breakthrough) with a known protein. Do that test when the column is new, to have a baseline of the binding capacity, and repeat the test after usage/ column regeneration. WebApr 8, 2024 · For this purpose, the Superdex 200 10/300 GL increase (Cytiva) column was used. In general, 500 μL – 1mL of purified protein was subjected to SEC using the Äkta chromatography systems (Cytiva). For this, the Superdex column was first equilibrated in the appropriate protein storage buffers (20 mM HEPES pH 8, 150 mM NaCl, 10% …

WebCalculate post-column pressure as total pressure minus pre-column pressure. If post-column pressure is higher than 3.5 bar, take steps to reduce it (shorten tubing, clear clogged tubing, or change flow restrictors), and perform steps 1–4 again until the post-column pressure is below 3.5 bar.
