Product Overview

Overview

Recently, there have been many researches applying magnetic beads in the field of biology: from cellular experiments and DNA purification to disease monitoring and even disease treatment. The surface of magnetic beads are coated with functional groups that allows binding of DNA, RNA, proteins, and specific cells. Afterwards, the beads are moved or attached to a desired position through external magnetic fields to perform purification. In addition, while conventional Magnetic Beads are micro-sized, this AccuNanoBeads™ is nano-sized, bearing the advantages of high binding capacity due to their relatively large surface area.

Technical/Specs

▶ Protein Purification Method by using Magnetic Nanobeads

Affter loading the protein sample to the tube, add the magnetic beads to combine them. Afterwards, fix the beads by using external magnetic field and wash the solution. Finally, elute the DNA or RNA from the magnetic beads. This method provides faster DNA purification than traditional ones.

▶ EDS Analysis of Magnetic Nanobeads

Figure 3. EDS analysis results of Magnetic Nanobeads. The results show that the Magnetic Nanobeads consist of silica and iron oxide.

▶ Size Distribution of Magnetic Nanobeads

Figure 4. Particle size distribution of Magnetic Nanobeads. The average size of the Magnetic Nanobeads is about 400 nm.

▶ Comparison of Protein Purification Beads

(b) SEM image of A company Magnetic Beads
(c) SEM image of B company Magnetic Beads
(d) SEM image of C company Magnetic Beads
(e) SEM image of D company Magnetic Beads

Figure 5 shows scanning electron microscope images of magnetic beads from Bioneer and a different company (b~e). Scanning electron microscope image of synthesized magnetic nanobeads shows that magnetic nanobeads of Bioneer is 400 nm size and spherical shape. However, the magnetic beads from the other company are micro meter size and various shape.

▶ Protein Purification Yield

Table 1 shows the protein purification yield of Bioneer Ni-NTA magnetic nanobeads. From these results, it can be seen that Bioneer magnetic nanobeads have a high protein purification yield of 77%. The protein used in the experiment was a 17kDa His-Tagged protein. The yield is the amount of target protein purified from the loading protein.
