The size-exclusion type of this chemical procedure is also used for proteins and is a low-resolution process that separates based on size.
The so-called 'fast-protein' type of this process is an important method for protein-purification, and often the associated resin contains Ni(II) ions that bind to His residues. The size-exclusion type of this chemical procedure is also used for proteins and is a low-resolution process that separates based on size. The high-performance liquid type of this process, along with other types, involves a mobile phase and a stationary phase. In the thin-layer type, retention factors can be calculated as the ratio of the migration distance of the mobile phase over that of the solvent front. For 10 points, name this procedure in chemistry involved in the separation of mixtures based on polarity.
