使用 EasySep™ 直接人 B-CLL 细胞分离试剂盒，可通过免疫磁性负选法直接从人全血样本中轻松高效地分离高纯度的 B 细胞慢性淋巴细胞白血病（B-CLL）细胞，无需密度梯度离心、沉降或红细胞裂解步骤。EasySep™ 技术在已发表研究中被广泛应用超过 20 年，结合了单克隆抗体的特异性与无柱磁系统的简便性。

在此 EasySep™ 负选步骤中，不需要的细胞通过抗体复合物和名为 EasySep™ Direct RapidSpheres™ 的磁性颗粒进行标记。以下标志物阳性的细胞将被去除：CD2、CD3、CD14、CD16、CD56、CD61 和 CD66b。经 EasySep™ 磁体分离后，带有磁性标记的不需要细胞被去除，未标记的目标 B-CLL 细胞通过倾倒或移液方式转移到新试管中。磁性细胞分离完成后，目标 B 细胞可直接用于流式细胞术、培养或 DNA/RNA 提取等下游应用。

实验数据

$Starting with human whole blood from normal healthy donors, the typical B cell (CD3-CD19+) content of the non-lysed final isolated fraction is 87.0 ± 7.6% (gated on CD45) or 84.1 ± 11.7% (not gated on CD45)$

Figure 1. Typical EasySep™ Direct Human B-CLL Cell Isolation Profile

Starting with human whole blood from normal healthy donors, the typical B cell (CD3-CD19+) content of the non-lysed final isolated fraction is 87.0 ± 7.6% (gated on CD45) or 84.1 ± 11.7% (not gated on CD45). In the example above, the B cell (CD3-CD19+) content of the lysed whole blood start and non-lysed final isolated fraction is 4.3% and 88.0% (gated on CD45), respectively, or 4.3% and 86.2% (not gated on CD45), respectively. The starting frequency of B cells in the non-lysed whole blood start sample above is 0.004% (data not shown). The purity of isolated cells is typically higher when processing samples that have an elevated starting frequency of B cells (e.g. CLL samples).

Cell Characterization

Can EasySep™ be used for either positive or negative selection?

Yes. The EasySep™ kits use either a negative selection approach by targeting and removing unwanted cells or a positive selection approach targeting desired cells. Depletion kits are also available for the removal of cells with a specific undesired marker (e.g. GlyA).

How does the separation work?

Magnetic particles are crosslinked to cells using Tetrameric Antibody Complexes (TAC). When placed in the EasySep™ Magnet, labeled cells migrate to the wall of the tube. The unlabeled cells are then poured off into a separate fraction.

Which columns do I use?

The EasySep™ procedure is column-free. That's right - no columns!

How can I analyze the purity of my enriched sample?

The Product Information Sheet provided with each EasySep™ kit contains detailed staining information.

Can EasySep™ separations be automated?

Yes. RoboSep™, the fully automated cell separator, automates all EasySep™ labeling and cell separation steps.

Can EasySep™ be used to isolate rare cells?

Yes. We recommend a cell concentration of 2x10⁸ cells/mL and a minimum working volume of 100 µL. Samples containing 2x10⁷ cells or fewer should be suspended in 100 µL of buffer.

Are the EasySep™ magnetic particles FACS-compatible?

Yes, the EasySep™ particles are flow cytometry-compatible, as they are very uniform in size and about 5000X smaller than other commercially available magnetic beads used with column-free systems.

Can the EasySep™ magnetic particles be removed after enrichment?

No, but due to the small size of these particles, they will not interfere with downstream applications.

Can I alter the separation time in the magnet?

Yes; however, this may impact the kit's performance. The provided EasySep™ protocols have already been optimized to balance purity, recovery and time spent on the isolation.

For positive selection, can I perform more than 3 separations to increase purity?

Yes, the purity of targeted cells will increase with additional rounds of separations; however, cell recovery will decrease.

How does the binding of the EasySep™ magnetic particle affect the cells? is the function of positively selected cells altered by the bound particles?

Hundreds of publications have used cells selected with EasySep™ positive selection kits for functional studies. Our in-house experiments also confirm that selected cells are not functionally altered by the EasySep™ magnetic particles.

If particle binding is a key concern, we offer two options for negative selection. The EasySep™ negative selection kits can isolate untouched cells with comparable purities, while RosetteSep™ can isolate untouched cells directly from whole blood without using particles or magnets.
