GST fusion protein purification magnetic bead is a new functional material designed for efficient and rapid purification of glutathione S-transferase (GST) fusion protein, which can be directly purified from biological samples in one step by magnetic separation, greatly simplifying the purification process and improving the purification efficiency. It is suitable for convenient purification of GST fusion protein in scientific and industrial fields.

Compared with the traditional column chromatography purification method, the purification of GST fusion protein by magnetic beads does not require multiple long-term high-speed centrifugation of crude protein samples, nor does it require filtration operations. There is no need to control the flow rate and no need for expensive chromatographic equipment. The specific binding of the sample to the magnetic bead, washing and elution of the target protein become very simple, fast and easy to operate, there is no bottleneck of sample flow rate control, and for skilled operators, high purity of the target protein can be obtained within one hour, which not only simplifies the process for researchers, saves time, reduces costs, and improves the purification efficiency of the target protein. The use of magnetic beads can easily achieve multi-sample parallel processing, achieve high throughput, and can also be arbitrarily enlarged sample purification scale.

Application example

1. Comparison of purification of GST fusion protein by magnetic beads and traditional chromatographic column

2%, 5%, 10%, 20% and 100% in the figure refer to the elution of magnetic beads after adsorption of target proteins with buffers containing 0.2mM, 0.5mM, 1mM and 10mM, respectively.

2. Parallel operation has high stability and can facilitate high throughput and large-scale protein purification

Results: CV(target protein purity) = 1.6%, CV(target protein load) = 4.5%.

In addition, when scaling up the sample purification, only the amount of magnetic beads can be increased in the same proportion, which does not affect the yield and purity of the target protein, and there is no restriction on the flow rate and sample volume, which is more suitable for large-scale protein purification production.

3. The product performance between different batches is stable, and the difference between batches is small
