EasySep™人T细胞分选试剂盒是EasySep™人T细胞富集试剂盒的新版（货号：19051），细胞分选更快速，短至8分钟即可完成免细胞磁珠分选。

CAR-T是一种通过基因工程改造T细胞对白血病的血液肿瘤细胞进行攻击的免疫疗法。截止今年十月，已有诺华和Kite两家公司获得FDA认证的唯二基因疗法。CAR-T免疫细胞疗法大热中。这两个临床成功的CAR-T疗法都对来自病人的外周血进行磁珠分选筛选T细胞。Stemcell的EasySep™人T细胞分选试剂盒可以用于CAR-T疗法的T细胞分选阶段（免疫磁珠细胞分选法）^2，3。EasySep™人T细胞分选试剂盒的磁珠分选采用负选方式，可以避免标记T细胞，以防标记抗体对T细胞造成伤害，zui大程度保持T细胞的untouched活性，立即用于下游CAR-T研究。

EasySep人T细胞分选试剂盒：适用样本

EasySep™人T细胞分选试剂盒可用于从各种样本来源中分选高纯度的人T细胞，包括：新鲜或冻存外周血单个核细胞（PBMCs）、白细胞单采术（Leuko Pak）样本。目标细胞被抗体复合物和磁珠标记，以进行负选。

诺华的CAR-T免疫细胞疗法使用同样的样本¹。

EasySep人T细胞分选试剂盒应用：CAR-T免疫细胞疗法流程的相关阶段

病人来源的T细胞样本（PBMC等）——T细胞分离（免疫细胞磁珠分选法，EasySep™人T细胞分选试剂盒）——CAR-T细胞活化、扩增和基因编辑——CAR-T细胞回输

其他应用

流式细胞术、细胞培养（CAR-T免疫疗法）或DNA/RNA提取

EasySep Human T Cell Isolation Kit组份

PBS - phosphate-buffered saline; TBS - TRIS-buffered saline

Components may be shipped at room temperature (15 - 25°C) but should be stored as indicated above.

EasySep人T细胞分选试剂盒：磁珠分选常规操作流程（负选）

1.将EasySep™分选抗体混合物加入到单细胞悬液中，并孵育3分钟

2.将EasySep™ RapidSpheres™ 加入到细胞悬液中。

3.将试管放置在EasySep™磁极（货号18000）中，并孵育3分钟。

4.将目标细胞倾倒至新的试管中。

*该时间是新一代的负选试剂盒所需的常规时间。每款试剂盒所需的实际时间取决于使用的磁极和分选流程。新一代的负选流程中无需磁珠孵育的步骤。

EasySep人T细胞磁珠分选试剂盒优点

方便快捷，新版短至8分钟。无柱分选

纯度zui高达98%

细胞保持Untouched

T细胞负选方案介绍

在负选时，非目标细胞通过针对细胞表面抗原的抗体被去除。负选试剂中的抗体组合确定哪些细胞被去除。

以下情况，比较适合负选：

需要未经标记的细胞

若将抗体结合到目标细胞上会造成抑制或活化，影响下游研究

目标细胞没有特异性抗体可用来标记

需要去除某些类型的细胞

英文版介绍Stemcell EasySep Human T Cell Isolation Kit

概要EasySep Human T Cell Isolation Kit

The EasySep™ Human T Cell Isolation Kit is designed to isolate T cells from fresh or previously frozen peripheral blood mononuclear cells by negative selection. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing non-T cells and dextran-coated magnetic particles. The labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are poured off into a new tube.

For even faster cell isolations, we recommend the new EasySep™ Human T Cell Isolation Kit (17951) which isolates cells in just 8 minutes.

Stemcell EasySep™人T细胞分选试剂盒说明书

描述EasySep Human T Cell Isolation Kit Description

Isolate untouched and highly purified T cells from fresh or previously frozen human peripheral blood mononuclear cells (PBMCs) or washed leukapheresis samples in as little as 8 minutes by immunomagnetic negative selection.

– Fast, easy-to-use and column-free

– Up to 98% purity with high recovery

– Untouched, viable cells

This kit targets non-T cells for removal with antibodies recognizing specific cell surface markers. Unwanted cells are labeled with antibodies and magnetic particles, and separated without columns using an EasySep™ magnet. Desired cells are simply poured off into a new tube. Isolated cells are immediay available for downstream applications such as flow cytometry, culture, or DNA/RNA extraction.

EasySep Human T Cell Isolation Kit-样本制备Sample Preparation

For available fresh and frozen samples, see www.stemcell。。ｃｏｍ/primarycells.

PERIPHERAL BLOOD

Prepare a PBMC suspension from whole blood by centrifugation over a density gradient medium (e.g. Lymphoprep™, Catalog #07801). For more rapid PBMC preparation, use the SepMate™ RUO (Catalog #86450/86415) or SepMate™ IVD* (Catalog #85450/85415) cell isolation tube.

If using previously frozen PBMCs, incubate the cells with DNase I Solution (Catalog #07900) at a concentration of 100 µg/mL at room temperature (15 - 25°C) for at least 15 minutes prior to labeling and separation. Filter aggregated suspensions through a 40 µm Cell Strainer (Catalog #27305) for optimal results.

After preparation, resuspend cells at 5 x 10^7 cells/mL in recommended medium.

* SepMate™ IVD is only available in select regions where it is registered as an In Vitro Diagnostic (IVD) device for the isolation of mononuclear cells (MNCs) from whole blood or bone marrow by density gradient centrifugation. In all other regions SepMate™ is available for research use only (RUO).

白细胞去除术LEUKAPHERESIS (LEUKO PAK)

Wash the peripheral blood leukapheresis sample by adding an equivalent volume of recommended medium or PBS containing 2% fetal bovine serum (FBS).

Centrifuge at 500 x g for 10 minutes at room temperature (15 - 25°C). Remove the supernatant and resuspend the cells at 5 x 10^7 cells/mL in recommended medium.

EasySep Human T Cell Isolation Kit推荐介质Recommended Medium

EasySep™ Buffer (Catalog #20144), RoboSep™ Buffer (Catalog #20104), or PBS containing 2% fetal bovine serum (FBS) and 1 mM EDTA. Medium should be free of Ca++ and Mg++.
