The micrometer magnetic bead series is a star product with high quality, meticulously crafted by a team of biological experts after years of research and development. Micron magnetic beads are designed and manufactured using a classic core-shell structure, with a polymer microsphere as the core and a magnetic material as the outer layer. The outermost layer is modified with a special polymer, which has the characteristics of uniform size distribution, high surface loading, short magnetic response time, and good dispersion stability. They can quickly and efficiently separate the tested substance from the sample, greatly improving detection efficiency.
Streptomyces avidin magnetic beads are fixed to the surface of the beads through covalent coupling technology, which can be used for the coupling of biotinylated nucleic acids, proteins, and other biological molecules. At present, this magnetic bead has been applied in chemiluminescence and targeted capture sequencing, and has received a stable number of customers. We look forward to more customers trying and adopting Dongna Bio's streptavidin magnetic beads.
Performance of Streptomyces avidin magnetic beads:
1.Magnetic beads with a particle size of 1 μ m. And uniform size and surface group distribution can ensure consistency in the hybridization capture process, making the library more standardized;
2.The surface of the magnetic beads is modified with hydrophilic polymer molecules and covalently coupled with multiple layers of streptavidin, which tightly encapsulates the surface of the magnetic beads, preventing magnetic particle leakage and greatly reducing non-specific adsorption, ensuring the specificity of hybridization capture;
3.The surface of magnetic beads has granular roughness, high specific surface area, and extremely high streptavidin loading, which can ensure a high adsorption capacity for labeled biotin probes;
4.Magnetic beads have good levitation properties and can maintain stability in environments ranging from pH 3.0 to 9.0, meeting the requirements of automated high-throughput during hybrid capture processes;
5.The magnetic beads have superparamagnetism, high magnetic content, and fast magnetic response, which can ensure the rapid and complete removal of streptavidin magnetic beads carrying empty probes after capture;
6.The stable yield of magnetic beads and high inter batch repeatability can ensure the stability of hybrid capture library construction.
