WebUltrafiltration involves forcing a protein solution through a membrane with a defined molecular weight cutoff. The protein does not pass through the membrane, whereas the other buffer components do. This method is usually relatively rapid and does not adversely affect the protein sample. Ultrafiltration is carried out by centrifugation. Websample while buffer exchange replaces the sample buffer with a new buffer. Gel filtration is one of the easiest chromatography methods to perform because samples are processed using isocratic elution. In its analytical form, gel filtration (also known as size exclusion chromatography) can distinguish between molecules (e.g. proteins) with a
