Dynabeads™ MAX EPEC/VTEC O121 试剂盒

Dynabeads磁珠是一种大小均一、无孔、超顺磁的、单分散的、高度交联的聚苯乙烯微球，整个磁珠由均匀分散的磁性材料构成。该磁性材料由磁赤铁矿(γ-Fe2O3)和磁铁矿(Fe3O4)的混合物组成。在Dynabeads磁珠M-280和M-450中，铁(Fe)分别占磁珠重量的12%和20%。Dynabeads磁珠表面覆盖有一层薄的聚苯乙烯外壳，将磁性材料包裹在内，可防止磁珠泄漏或在内部捕获配体。此外，该外壳也可避免目标分子直接接触铁，同时为每次实验提供特定的表面来吸附或偶联各种分子。
磁珠尺寸和形状均一，确保物理和化学性质稳定一致，进而提高实验结果的质量和可重复性。
Dynabeads磁珠分为3种不同尺寸：4.5 μm （M-450磁珠），2.8 μm （M-270/M-280磁珠）和1 μm （MyOne磁珠）。

Dynabeads 磁珠微生物富集产品具有下列优势：

•实验方案简单
•经济实惠
•可稳定储存
•易于质控
•高灵敏度
•节约时间（对于加工食品中的Salmonella，由于免疫磁性分析（IMS）代替了传统的选择性富集的方法，该检测比标准方法快了24小时；同时由于已经获得了分离的菌落，也节约了确认步骤的时间）

Dynabeads magnetic beads are uniform, non-porous, superparamagnetic, monodispersed and highly cross-linked polystyrene microspheres consisting of an even dispersion of magnetic material throughout the bead. The magnetic material within the Dynabeads magnetic beads consists of a mixture of maghemite (gamma-Fe2O3) and magnetite (Fe3O4). The iron content (Fe) of the beads is 12% by weight in Dynabeads magnetic beads M-280 and 20% by weight in Dynabeads magnetic beads M-450. The Dynabeads magnetic beads are coated with a thin polystyrene shell which encases the magnetic material, and prevents any leakage from the beads or trapping of ligands in the bead interior. The shell also protects the target from exposure to iron while providing a defined surface area for the adsorption or coupling of various molecules.

Uniformity of bead size and shape provides consistent physical and chemical properties. These uniform physical characteristics lead to high-quality, reproducible results.

The Dynabeads magnetic beads are available in three different sizes: 4.5 µm (M-450 beads), 2.8 µm (M-270/M-280 beads) and 1 µm (MyOne beads).

Dynabeads magnetic beads microbiology enrichment products offer the following advantages:

Simple protocol
Cost effective
Shelf-stable reagents
Easy QC
High sensitivity
Saves time (for Salmonella in processed food, the assay is 24 hours faster compared to standard methods because immunomagnetic separation (IMS) replaces conventional selective enrichment; also saves time in confirmation procedure because you already have the colony isolated)

The M stands for magnetic. M-280 refers to hydrophobic 2.8 micron beads, while M-270 refers to hydrophilic 2.8 micron beads. MyOne refers to 1 micron beads.
