The ion-exchange process, in which beads with bound water are exchanged with beads without ligands, is a popular method.
In complicated mixtures, Protein A affinity chromatography may also distinguish between distinct proline and glycine bound residues. Another method for protein purification is recombinant protein A. It can eliminate contaminants in complex protein tests and may be appropriate for low-protein-concentration applications. As a result, accuracy and speed are increased.
Protein A Resin is frequently used in place of other methods for separating protein from mixtures. Protein A purified product containing one molecule of each purified protein is obtained using affinity chromatography. Because it relies on the affinity of molecules for each other, this method is favoured above others like electrophoresis.
