Lymphoprep™ is a ready-made, sterile, endotoxin-tested, separation medium for isolating human mononuclear cells (lymphocytes and monocytes), especially from blood. Relatively low buoyant density (below 1.077 g/ml) mononuclear cells are retained at the sample/medium interface while more dense erythrocytes and polymorphonuclear leukocytes (PMNs or granulocytes) sediment through the medium.

Why Payque more?

Lymphoprep™ has the same specifications as Ficoll(R)-Paque and Histopaque(R)-1077 and is manufactured to essentially equivalent quality standards. As compared to top brands, Lymphoprep™ can save up to 50% on gradient medium.

About Lymphoprep™

A simple and effective method for the isolation of mononuclear cells from human blood was reported by Dr. Arne Bøyum in 1968. For more than 35 years Lymphoprep™ medium has been widely used for isolating mononuclear cells (monocytes and lymphocytes) by exploiting their low buoyant density (below 1.077 g/ml) as compared to erythrocytes and polymorphonuclear (PMN) leukocytes (granulocytes). Mononuclear cells are retained at the sample/medium interface while erythrocytes and PMNs sediment through the medium.

The described method is rapid, simple and reliable and gives excellent results with blood samples from normal individuals and patients. To obtain maximum yields it is important that blood samples are diluted 1:1 with physiological saline before being applied to Lymphoprep™. Erythrocyte contamination in mononuclear cell suspensions is usually between 3-10% of the total cell number. Some immature PMNs may sediment with lymphocytes during intense immunosuppressive therapy. Removal of most platelets from mononuclear cell preparations is essential to avoid inhibition in cytotoxicity tests. Lymphoprep™ can be used for the preparation of pure lymphocyte suspensions for tissue typing, anti-lymphocyte sera and immunological research. Thorsby and Brattelie used this technique with only slight modifications in the preparation of pure lymphocyte suspensions for cytotoxicity tests and lymphocyte cultures.

Each batch of Lymphoprep™ is assessed for endotoxin level using a specific LAL test. Axis-Shield's goal is to produce batches with an endotoxin level lower or equal to 0.13 EU/ml.
