His-tag protein purification beads posses superparamagnetism, it is a new functional material designed for efficient and rapid purification of His-tag protein. It can extract the target protein with high purity from the biological samples in one step using magnetic separation method and it greatly simplifies the purification process and improves the efficiency of purification. This method is suitable for scientific research and industrial areas to facilitate the purification of his-tag protein.

Compared with the traditional tomographic method which use metal chelate agarose prepacked column, our His-tag Protein Purification beads do not need to carry out high-speed centrifugation and filter filtration on the crude protein samples for a long time, or control the flow rate, and do not need the expensive chromatography equipment. The specific binding of the sample to the magnetic beads, following washing and target protein elution become very simple, fast and easy to operate. For skilled operators, highly purified protein can be obtained within 1 hour, and parallel processing of high throughput and large amount samples can be easily achieved to save researchers time and cost.
