The EasySep® Human Whole Blood CD138 Positive Selection Kit is designed to isolate CD138+ (syndecan-1) cells from whole blood by positive selection. Desired cells are targeted with Tetrameric Antibody Complexes recognizing CD138 and dextran-coated magnetic particles. The cocktail also contains an antibody to human Fc receptor to minimize nonspecific binding. Labeled cells are separated using an EasySep® magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off. The CD138 antigen is expressed on normal and malignant plasma cells (but not mature B cells).

FAQS:


  • HOW EASYSEP™ WORKS

    • Q. CAN EASYSEP™ BE USED FOR EITHER POSITIVE OR NEGATIVE SELECTION?
      A. 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).
    • Q. HOW DOES THE SEPARATION WORK?
      A. 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.
    • Q. WHICH COLUMNS DO I USE?
      A. The EasySep™ procedure is column-free. That's right - no columns!
    • Q. HOW CAN I ANALYZE THE PURITY OF MY ENRICHED SAMPLE?
      A. The Product Information Sheet provided with each EasySep™ kit contains detailed staining information.
    • Q. CAN EASYSEP™ SEPARATIONS BE AUTOMATED?
      A. Yes. RoboSep™, the fully automated cell separator, automates all EasySep™ labeling and cell separation steps.
    • Q. CAN EASYSEP™ BE USED TO ISOLATE RARE CELLS?
      A. 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.

    EASYSEP™ MAGNETIC PARTICLES

    • Q. ARE THE EASYSEP™ MAGNETIC PARTICLES FACS-COMPATIBLE?
      A. 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.
    • Q. CAN THE EASYSEP™ MAGNETIC PARTICLES BE REMOVED AFTER ENRICHMENT?
      A. No, but due to the small size of these particles, they will not interfere with downstream applications.
    • Q. HOW DOES THE BINDING OF THE EASYSEP™ MAGNETIC PARTICLE AFFECT THE CELLS? IS THE FUNCTION OF POSITIVELY SELECTED CELLS ALTERED BY THE BOUND PARTICLES?
      A. 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.

    MODIFYING THE EASYSEP™ PROTOCOL

    • Q. CAN I ALTER THE SEPARATION TIME IN THE MAGNET?
      A. 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.
    • Q. FOR POSITIVE SELECTION, CAN I PERFORM MORE THAN 3 SEPARATIONS TO INCREASE PURITY?
      A. Yes, the purity of targeted cells will increase with additional rounds of separations; however, cell recovery will decrease.
