  • 2_lymphopure_FC_1and2and3_111617
    Forward and side scatter profile of human lymphocytes after peripheral blood centrifugation with Lymphopure™ (top dot plot), an equivalent product (middle plot), or no separation (bottom plot, lysed blood).
  • 3_lymphopure_FC_4and5_111617
    Histogram overlay shows CD3 or CD15 profile on total cells from lysed peripheral human blood before (dotted histogram) and after Lymphopure™ (purple tinted histogram) or equivalent product (orange open histogram) centrifugation. CD3 is a molecule expressed by T cells, which are recovered with the use of the isolation media. CD15 is a molecule highly expressed by granulocytes, which are absent after isolation with Lymphopure™.
  • 4_lymphopure_Diagram_111617
    Diagram showing whole blood cell separation using Lymphopure™. Blood is diluted with saline buffer and carefully layered over the medium in a conical tube, avoiding disturbing the interphase. Following centrifugation, at the appropriate speed with no braking, well-defined phases can be observed: 1-plasma, 2-interphase with mononuclear cells, 3-centrifugation medium, and 4-erythrocytes and granulocytes. Cells of interest can be aspirated from the interphase.

Lymphopure™ is a ready-to-use filtered and endotoxin tested solution for the isolation of mononuclear cells (MNCs) from a cell suspension. The solution is formulated at a density that allows separation of MNCs from other cells in blood such as granulocytes and erythrocytes. Granulocytes and erythrocytes will sediment after centrifugation.

Recommended Usage

Watch a video protocol.

  1. Collect blood into a tube containing anti-coagulant (EDTA, heparin)
  2. Dilute the blood with an equal volume of phosphate-buffered saline or similar suitable medium.
  3. Mix Lymphopure™ by inverting the bottle several times.
  4. Aliquot half the amount of Lymphopure™ into a tube. For every ml of diluted blood, add 0.5 ml of Lymphopure™.
  5. Carefully layer the diluted blood on top of Lymphopure™. Avoid mixing blood with Lymphopure™.
  6. Centrifuge at 800 x g for 20 minutes at room temperature (15 - 25°C) without braking. If the blood has been stored for more than 2 hours, centrifuge for 30 minutes.
  7. After centrifugation, mononuclear cells (MNCs) form a defined cell layer at the plasma: Lymphopure™ interface.
  8. Collect the MNC layer at the interface without disturbing the other fractions.
  9. Wash MNCs with medium.
