人全血CD34+细胞完全试剂盒是一种简单的两步法，用于从全血或白膜层中分离CD34+细胞。

首先，使用RosetteSep™人造血祖细胞富集抗体混合物 (产品号 #15186C)预富集造血祖细胞，包含可识别CD2, CD3, CD14, CD16, CD19, CD24, CD56, CD66b和CD61细胞表面标志物的抗体。然后使用EasySep™人CD34正选抗体混合物 (产品号 #18066C) 来分选CD34+细胞，其中包含识别CD34的抗体。RosetteSep™将非目的细胞与红细胞 (RBCs) 交联，形成免疫玫瑰花环，并在密度梯度离心时沉降。含CD34+细胞的预富集组分可从血浆和密度梯度离心液介质的界面收集。预富集的CD34+细胞随后用抗体和磁珠标记，并通过EasySep™磁极，无需分离柱分选。非目的细胞通过简单倾倒弃去，而目的细胞则保留在管中。分选后的CD34+细胞可立即用于下游应用。

Data Figures

Figure 1.Typical CD34 Selection Profile on Human Whole Blood

Starting with whole peripheral blood, the CD34+ cell content of the isolated fraction is typically 95.1 ± 4.5% (gated on viable CD45+ cells; mean ± SD for the silver “The Big Easy” EasySep™ Magnet). In the above example, the purities of the start and final isolated fractions are 0.06% and 96.2%, respectively.

Isolate Cells with a Simple Pour-Off: EasySep™ Cell Separation Technology

Frequently Asked Questions

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.

Nucleosome Density ChIP-Seq Identifies Distinct Chromatin Modification Signatures Associated with MNase Accessibility. Lorzadeh A et al. Cell reports 2016 NOV

Abstract

Nucleosome position, density, and post-translational modification are widely accepted components of mechanisms regulating DNA transcription but still incompletely understood. We present a modified native ChIP-seq method combined with an analytical framework that allows MNase accessibility to be integrated with histone modification profiles. Application of this methodology to the primitive (CD34+) subset of normal human cord blood cells enabled genomic regions enriched in one versus two nucleosomes marked by histone 3 lysine 4 trimethylation (H3K4me3) and/or histone 3 lysine 27 trimethylation (H3K27me3) to be associated with their transcriptional and DNA methylation states. From this analysis, we defined four classes of promoter-specific profiles and demonstrated that a majority of bivalent marked promoters are heterogeneously marked at a single-cell level in this primitive cell type. Interestingly, extension of this approach to human embryonic stem cells revealed an altered relationship between chromatin modification state and nucleosome content at promoters, suggesting developmental stage-specific organization of histone methylation states.
