Here, protocols for purification of His-tagged proteins under native, as well as under denaturing conditions, are given. Ni nta qiagen choice whether to purify the target protein under native or denaturing conditions depends on protein location and solubility, the accessibility of the His tag, and the desired downstream application.

The most economical method to purify protein from multiple ni nta qiagen lysates is to use the appropriate resin in multiple columns or a multi-well plate and manually purify under gravity.

The time can be shortened by using the batch method, where the purification takes place in a tube or multi-well plate and is spun in a centrifuge after each step, allowing the resin to separate at the bottom more quickly [ 5 ni nta qiagen.

A vacuum manifold can also be used to perform the purification on the bench, which can further speed up each step [ 15 ].

  • A semi-automated method for purification of milligram quantities of proteins on the QIAcube

This allows one-step protein purification under either native or denaturing conditions, from dilute solutions and crude lysates. Strong denaturants and detergents can be used for efficient solubilization and purification of receptors, membrane proteins, and proteins that form inclusion bodies.

Reagents that allow efficient removal of nonspecifically binding contaminants can be included in wash buffers see table.

The QIAcube is a robotic workstation for the automatic purification of nucleic acid and ni nta qiagen, consisting of a micro-centrifuge, a robotic arm that ni nta qiagen a micro-pipetor and a gripper to transfer spin columns as well as a micro-tube incubator and shaker Figure 1.

It accepts ni nta qiagen to 12 micro-tube samples and up to 9 different purification solutions to automatically pipette, mix, incubate, transfer and spin in order to purify nucleic acid or protein.

It accepts all of the ni nta qiagen established Qiagen spin column kits and runs them automatically after the user includes the samples to be purified, the kit specific buffers, tips and rotor adapters with spin column in appropriate position.
