StemCell 19051 CAR-T免疫細(xì)胞磁珠分選試劑盒產(chǎn)品
閱讀：4379發(fā)布時(shí)間：2017-11-2
EasySep™人T細(xì)胞富集試劑盒可用于從新鮮或凍存外周血單個(gè)核細(xì)胞中通過(guò)負(fù)選方式分離T細(xì)胞。不需要的細(xì)胞被識(shí)別非T細(xì)胞的四聚體抗體復(fù)合物（Tetrameric Antibody Complexes）和dextran包被的磁珠標(biāo)記后移除。被標(biāo)記細(xì)胞不需要過(guò)柱，使用EasySep™磁極就能簡(jiǎn)單分離。需要的細(xì)胞被倒到新管子。分離細(xì)胞可以立即用于下游：流式細(xì)胞術(shù)、細(xì)胞培養(yǎng)（CAR-T免疫療法）或DNA/RNA提取。
推薦使用新版EasySep™人T細(xì)胞分選試劑盒（貨號(hào)：17951），短至8分鐘即可完成免疫磁珠細(xì)胞分選。
CAR-T是一種通過(guò)基因工程改造T細(xì)胞對(duì)白血病的血液腫瘤細(xì)胞進(jìn)行攻擊的免疫療法。截止今年十月，已有諾華和Kite兩家公司獲得FDA認(rèn)證的唯二基因療法。CAR-T免疫細(xì)胞療法大熱中。這兩個(gè)臨床成功的CAR-T療法都對(duì)來(lái)自病人的外周血T細(xì)胞進(jìn)行分選。Stemcell的EasySep™人T細(xì)胞富集試劑盒可以用于CAR-T療法的T細(xì)胞分選階段（免疫磁珠細(xì)胞分選法）2，3。EasySep™人T細(xì)胞富集試劑盒的磁珠分選采用負(fù)選方式，可以避免標(biāo)記T細(xì)胞，以防標(biāo)記抗體對(duì)T細(xì)胞造成傷害，zui大程度保持T細(xì)胞的untouched活性，立即用于下游CAR-T研究。

*該時(shí)間是新一代的負(fù)選試劑盒所需的常規(guī)時(shí)間。每款試劑盒所需的實(shí)際時(shí)間取決于使用的磁極和分選流程。新一代的負(fù)選流程中無(wú)需磁珠孵育的步驟。
T細(xì)胞負(fù)選方案介紹
在負(fù)選時(shí)，非目標(biāo)細(xì)胞通過(guò)針對(duì)細(xì)胞表面抗原的抗體被去除。負(fù)選試劑中的抗體組合確定哪些細(xì)胞被去除。
以下情況，比較適合負(fù)選：
需要未經(jīng)標(biāo)記的細(xì)胞
若將抗體結(jié)合到目標(biāo)細(xì)胞上會(huì)造成抑制或活化，影響下游研究
目標(biāo)細(xì)胞沒(méi)有特異性抗體可用來(lái)標(biāo)記

Stemcell EasySep Human T Cell Enrichment Kit英文版介紹
概要
The EasySep™ Human T Cell Enrichment 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細(xì)胞富集試劑盒說(shuō)明書
Description
Isolate untouched and highly purified T cells from fresh or previously frozen human peripheral blood mononuclear cells (PBMCs) or lysed leukapheresis samples
by immunomagnetic negative selection.
– Fast, easy-to-use and column-free
– Up to 99% purity
– Untouched, viable cells
EasySep™ Human T Cell Enrichment 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 Enrichment Kit-樣本制備Sample Preparation
PERIPHERAL BLOOD
Prepare a PBMC suspension from whole peripheral 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).
白細(xì)胞去除術(shù)LEUKAPHERESIS (LEUKO PAK)
If working with large volumes (> 150 mL), concentrate leukapheresis cells first by centrifuging at 500 x g for 10 minutes. Remove the supernatant and resuspend the cells in 1/10th of the original leukapheresis volume with recommended medium (e.g. for 300 mL of cells, resuspend in 30 mL of recommended medium). For small volumes (≤ 150 mL), add Ammonium Chloride Solution (Catalog #07800) directly to the leukapheresis sample.
1. Add an equal volume of Ammonium Chloride Solution to the leukapheresis sample.
2. Incubate on ice for 15 minutes.
3. Centrifuge at 500 x g for 10 minutes at room temperature (15 - 25°C). Remove the supernatant.
4. Wash the cells by topping up the tube with recommended medium. Centrifuge the cells at 150 x g for 10 minutes at room temperature with the brake off.
Carefully remove the supernatant.
5. Repeat step 4 one or more times until most of the plaets have been removed (indicated by a clear supernatant).
6. Resuspend the cells at 5 x 10^7 cells/mL in recommended medium.
EasySep™ Human T Cell Enrichment Kit推薦介質(zhì)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++.
