In particular, the method comprises the step of using of a depth filtration prior to an ion-exchange chromatography.

Then the collected DNA is subjected to gel filtration chromatography and ion exchange chromatography to thereby purify the environmental sample-origin DNA.

The invention relates to the purification of biological macromolecules from biological feedstocks by means of ion exchange chromatography.

Provided are methods of using ion exchange based chromatography to control the levels of high mannose glycoforms in a glycoprotein sample, such as an antibody sample.

More advacned methods of ion-exchange chromatography have since been developed which employ low temperature/acids so as to prevent denaturation.

The present invention relates to a purification process of (Aib8,35)GLP-1(7-36)NH2 comprising an ion-exchange chromatography purification step and a reversed phase HPLC purification step.

Ion-exchange chromatography is a commonly used process to manufacture whey protein isolate, which contains a high level of protein, i.e. >90%.

In one embodiment the anion exchange chromatography material is a membrane anion exchange chromatography material.

A method for purifying viruses from a cell line culture by chromatography, comprising an anion exchange chromatography step followed by a cation exchange chromatography step and optionally a metal-binding affinity chromatography step.

The suspension is decontaminated by column chromatography over agarose.

Chromatographic purification was obtained by a strong anionic exchange resin.

It further provides for optional additional purification steps, including lysate filtration, anion exchange chromatography, triplex affinity chromatography, and hydrophobic interaction chromatography.

A process for producing a sodium titanate is utilized in an ion exchange media.
