General term for the transfer of protein, RNA or DNA molecules from a relatively thick acrylamide or agarose gel to a paper-like membrane (usually nylon or nitrocellulose) by capillarity or an electric field, preserving the spatial arrangment. Once on the membrane, the molecules are immobilized, typically by baking or by ultraviolet irradiation, and can then be detected at high sensitivity by hybridization (in the case of DNA and RNA), or antibody labelling (in the case of protein). RNA blots are called Northern blots; DNA blots, Southern; protein blots, Western. See also dot and slot blots.
