Humana Press New York NY. First Online 05 August 2014. Introduction Live peripheral blood mononuclear cells PBMCs can be frozen and thawed for later analyses by adding and removing a cryoprotectant such as dimethyl sulfoxide DMSO.

Laboratories across the world use various procedures but published evidence of optimal thawing procedures is scarce. The separation of PBMC peripheral blood mononuclear cells is essential for all subsequent analyses in immune monitoring. Without an effective and careful isolation freezing and thawing of the cells immune monitoring will be not successful and will not provide reliable results especially for antigen-specific T cells with lower frequency in the circulation.

For separation of mononuclear cells from whole. Peripheral blood mononuclear cells PBMC were isolated by Ficoll-Paque density gradient centrifugation GE Healthcare Europe Velizy France. PBMC were immediately processed for flow cytometry analysis or frozen in fetal bovine serum75 DMSO Sigma Saint Louis USA and conserved in liquid nitrogen for 3 months.

The cells most sensitive to freezing and thawing procedure seem to be dendritic cells DC and their precursors which are of the most potent antigen-presenting cells. The authors investigated and established a method of cryopreserving fresh PBMC from which DC were recovered and differentiated efficiently by using recombinant r GM-CSF and rIL-4. It was the purpose of this study to establish and evaluate a freezing-and-thawing method for preservation of hemopoietic stem cells from the peripheral blood.

Blood leukocytes collected by means of an IBM Blood-Cell-Separator were frozen in plastic bags. Peripheral blood mononuclear cells PBMCs are valuable for both clinical and research applications. Isolating pure populations of PBMCs from whole blood traditionally requires sample dilution and use of a density gradient medium to deplete red blood cells RBC granulocytes GRN and platelets PLT1 This open manual.

Introduction Live peripheral blood mononuclear cells PBMCs can be frozen and thawed for later analyses by adding and removing a cryoprotectant such as dimethyl sulfoxide DMSO. Laboratories across the world use various procedures but published evidence of optimal thawing procedures is scarce.

Materials and methods PBMCs were separated from blood collected from healthy Danish blood. Human PBMC are isolated using a density gradient technique. The two most commonly used density gradient solutions are Ficoll-Paque PLUS from GE Healthcare Life Sciences and Histopaque-1077 from Sigma Aldrich.

The separation can be done in either 15 or 50 ml conical tubes. The quality of peripheral blood mononuclear cells PBMCs isolated from whole blood has a significant impact on their subsequent analysis. Maximizing recovery viability and functionality of isolated PBMCs is essential to the reliability and consistency of downstream applications particularly within cell therapy manufacturing.

Frozen per the manufacturers recommendation in its original container and can be used until the manufacturers expiration date. Once thawed FBS can be stored at 2 to 8C and. Annonse sterile-filtered suitable for cell culture.
