Gel permeation chromatography Wikipedia

Separation on the basis of size- Gel Filtration chromatography: Proteins of different sizes are separated on a column in which the stationary phase is an polymerized agarose or acrylamide bead, which contain pores of various sizes.

how to find available distribution coefficient gel filtration

Lab Protein separation and analysis Uppsala University

On the other hand, we consider that the distribution coefficient obtained in static equilibrium experiments should be determined by the translational frictional coefficient-based Stokes radius, since the solvent does not flow. On this basis, we discuss the meaning of the Stokes radius and the separation mechanism of macromolecules by gel filtration.

Experiment 3. Protein Size Harvard University

gel filtration can be effective but have limitations. Dialysis procedures can take up to several days, require large volumes of water for equilibration and risk product loss through manual manipulation of the dialysis bags. Gel filtration results in a dilution of the sample and often requires an additional ultrafiltration step to concentrate it back. Adding steps to a process can risk sample

Gel filtration is used to separate proteins of different sizes. You may also determine the native molecular weight of a protein by this method since there is a linear correlation between the elution volume of proteins and the logarithms of their molecular weights (MW) The system contains two phases, one stationary and one mobile. The stationary phase usually consists of a cross-linked
