Overview

The EasySep™ Human Progenitor Cell Enrichment Kit with Platelet Depletion is designed to isolate hematopoietic progenitor cells from fresh or previously frozen cord blood and other cell preparations that contain large numbers of platelets by negative selection. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing CD2, CD3, CD11b, CD11c, CD14, CD16, CD19, CD24, CD56, CD61, CD66b, glycophorin A 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.
Advantages:
• Fast, easy-to-use and column-free

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.

Starting with Nucleated Cells, the CD34+ Cell Content of the Enriched Fraction Typically Ranges from 50 - 75% Depending on the Quality of the Start Sample

Figure 1. Typical EasySep™ Human Progenitor Cell Enrichment Kit with Platelet Depletion Profile

Starting with nucleated cells, the CD34+ cell content of the enriched fraction typically ranges from 50 - 75%, depending on the quality of the start sample. Note: CD34+ enrichment is dependent on the frequency of CD34+ cells in the start sample, which is variable between cord blood samples. Use of poor quality cord blood or frozen samples may result in lower CD34+ cell content of the enriched fraction.

Activation of the receptor tyrosine kinase, RET, improves long-term hematopoietic stem cell outgrowth and potency.

W. Grey et al.

Abstract

Expansion of Human Hematopoietic Stem Cells (HSCs) is a rapidly advancing field showing great promise for clinical applications. Recent evidence has implicated the nervous system and glial family ligands (GFLs) as potential drivers of hematopoietic survival and self-renewal in the bone marrow niche, but how to apply this to HSC maintenance and expansion is yet to be explored. We demonstrate a role for the GFL receptor, RET, at the cell surface of HSCs, in mediating sustained cellular growth, resistance to stress and improved cell survival throughout in vitro expansion. HSCs treated with the key RET ligand/co-receptor complex, GDNF/GFRa1, show improved progenitor function at primary transplantation and improved long-term HSC function at secondary transplantation. Finally, we demonstrate that RET drives a multi-faceted intracellular signalling pathway, including key signalling intermediates AKT, ERK1/2, NFkB and p53, responsible for a wide range of cellular and genetic responses which improve cell growth and survival under culture conditions.

Spironolactone inhibits the growth of cancer stem cells by impairing DNA damage response.

A. Gold et al.

Abstract

The cancer stem cell (CSC) model suggests that a subpopulation of cells within the tumor, the CSCs, is responsible for cancer relapse and metastasis formation. CSCs hold unique characteristics, such as self-renewal, differentiation abilities, and resistance to chemotherapy, raising the need for discovering drugs that target CSCs. Previously we have found that the antihypertensive drug spironolactone impairs DNA damage response in cancer cells. Here we show that spironolactone, apart from inhibiting cancerous cell growth, is also highly toxic to CSCs. Notably, we demonstrate that CSCs have high basal levels of DNA double-strand breaks (DSBs). Mechanistically, we reveal that spironolactone does not damage the DNA but impairs DSB repair and induces apoptosis in cancer cells and CSCs while sparing healthy cells. In vivo, spironolactone treatment reduced the size and CSC content of tumors. Overall, we suggest spironolactone as an anticancer reagent, toxic to both cancer cells and, particularly to, CSCs.
