In biomedical sciences it is normally regarded as a reduced resolution chromatography and so it is frequently reserved for the final, "sharpening" move of the purification. It's also valuable for figuring out the tertiary construction and quaternary structure of purified proteins. SEC is employed primarily for your Examination of enormous molecules such as proteins or polymers.
Just after utilizing the column, it is usually advised to scrub the column prior to storing it. The cleansing procedure normally consists of applying an isocratic/gradient clean that's closest to the final solvent procedure on the column
