Overview

The EasySep™ RBC Depletion Reagent is designed to immunomagnetically deplete red blood cells (RBCs) from fresh human peripheral blood, umbilical cord blood, bone marrow or leukapheresis samples by negative selection. RBCs are targeted with Tetrameric Antibody Complexes recognizing Glycophorin A and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet without the use of columns. Unwanted cells remain in the tube while desired cells are poured off.

This product replaces the EasySep™ Human Glycophorin A Depletion Kit (Catalog #18352) for even faster cell isolations.
Advantages:
The benefits of this kit include:
• 99.9% RBC depletion without the need for density gradient centrifugation, sedimentation or lysis
• Fast, easy-to-use and column-free
• Isolated cells are untouched

Figure 1. EasySep™ RBC Depletion Reagent Provides Superior RBC Depletion Compared to Ammonium Chloride Lysis

Different types of RBC-containing samples from normal healthy donors were processed to remove RBCs by using either ammonium chloride (NH4Cl) lysis or immunomagnetic depletion with EasySep™ RBC Depletion Reagent. After RBC removal, samples were stained with fluorochrome-conjugated anti-CD45 and anti-Glycophorin A antibodies and analyzed by flow cytometry. Residual RBCs were identified as Glycophorin A+/CD45 events. (A) The percentages of residual RBCs in various samples following use of EasySep™ RBC Depletion Reagent was significantly lower compared to samples treated with ammonium chloride (mean ± SD; n = 31). (B) Both, RBC lysis with ammonium chloride and RBC removal using EasySep™ RBC Depletion Reagent resulted in an equivalent total number of white blood cells recovered from whole blood samples (mean ± SD; n = 37).

Figure 2. Typical RBC Removal Using EasySep™ RBC Depletion Reagent With Human Whole Blood Samples

Starting with human whole blood from normal healthy donors, the percentage of residual RBCs (Glycophorin A+/CD45-) following use of EasySep™ RBC Depletion Reagent is typically 2 ± 3 (mean ± SD; n = 31). In the above example, the residual RBC content is 0.05%.

Figure 3. Typical RBC Removal Using EasySep™ RBC Depletion Reagent With Human Bone Marrow Samples

Starting with human bone marrow, the percentage of residual RBCs (Glycophorin A+/CD45-) following use of EasySep™ RBC Depletion Reagent is typically 0.39 ± 0.34 (mean ± SD; n = 5). In the above example, the residual RBC content is 0.57%.

Figure 4. Typical RBC Removal Using EasySep™ RBC Depletion Reagent With Buffy Coat Samples

Starting with buffy coat, the percentage of residual RBCs (Glycophorin A+/CD45-) following use of EasySep™ RBC Depletion Reagent is typically 0.12 ± 0.08 (mean ± SD; n = 6). In the above example, the residual RBC content is 0.26%.

Figure 5. Typical RBC Removal Using EasySep™ RBC Depletion Reagent With Cord Blood Samples

Starting with cord blood, the percentage of residual RBCs (Glycophorin A+/CD45-) following use of EasySep™ RBC Depletion Reagent is typically 1.7 ± 2.2 (mean ± SD; n = 16). In the above example, the residual RBC content is 0.08%.

Figure 6. Typical RBC Removal Using EasySep™ RBC Depletion Reagent With Leukapheresis Samples

Starting with leukapheresis samples, the percentage of residual RBCs (Glycophorin A+/CD45-) following use of EasySep™ RBC Depletion Reagent is typically 0.5 ± 0.8 (mean ± SD; n = 15). In the above example, the residual RBC content is 0.6%.
