   Spin column-based nucleic acid purification is a method of purifying DNA, RNA or plasmid from a sample using a spin column filter. [25] The method is based on the principle of selectively binding nucleic acids to a solid matrix in the spin column, while other contaminants, such as proteins and salts, are washed away. The conditions are then ...

9. Desalting and buffer exchange - Wikipedia

   en.wikipedia.org/wiki/Desalting_and_buffer_exchange

   Gravity-flow, or drip, columns use head-pressure from a buffer-chase to push the sample through the gel filtration matrix. Sample is loaded into the top of an upright column and allowed to flow into the resin bed. The sample is then chased through the column by adding additional buffer or water to the top of the column.
