The methods of Whitaker and Andrews are used for determining molecular weight with this technique, which frequently involves the use of dextran blue as a void volume marker.  
The alternate recycling type of this technique has been applied to the study of gold nanocrystals.  The methods of Whitaker and Andrews are used for determining molecular weight with this technique, which frequently involves the use of dextran blue as a void volume marker.  Desalting apparati like G-twenty-fives, use the same matrix as this technique, and it is useful for studying ligand-binding because ligand-bound protein elutes earlier than unbound protein. This type of column chromatography tends to dilute samples because it does not involve adsorption or gradient elution, and it is often used to distinguish protein monomers from oligomeric complexes.  For 10 points, name this type of chromatography in which porous sepharose beads are used to separate proteins by mass.
