CD34 is a glycosylated transmembrane protein and represents a well-known marker for primitive blood- and bone marrow-derived progenitor cells, especially for hematopoietic and endothelial stem cells. CD34+ stem cells are multipotent and can differentiate to all hematopoietic cell types in blood.  CD34+ cells can also give rise to all lymphohematopoietic lineages even though they comprise only a small percentage of the cell population.

Our CD34+ cells are isolated using positive immunomagnetic cell separation procedures from single or mixed healthy donors. All cord blood is collected in Citric Phosphate with Dextrose Buffer (CPD)  from fully consented IRB approved donors.

CD34 is a cluster of differentiation (CD) first described independently by Civin et al. and Tindle et al.[6][7][8][9] in a cell surface glycoprotein and functions as a cell-cell adhesion factor. It may also mediate the attachment of stem cells to bone marrow extracellular matrix or directly to stromal cells.

Cat#: PBMC-C100M (Frozen, 100 million/vial)

가능 용량 : 10M, 20M, 50M, 300M, 500M, 2B, 4B cells/vials

Human Peripheral Blood Mononuclear Cells (PBMCs) are blood cells with a single round nucleus. These cells include lymphocytes (T, B and NK cells), monocytes and dendritic cells.  PBMCs are parts of the immune system which are critical to cell-mediated and humoral immunity. Our Human PBMCs are isolated from normal healthy donor leukopaks collected in acid-citrate-dextrose formula A (ACDA) as an anticoagulant. All donors must be tested negative for HBV, HCV, HIV and Syphilis and are IRB consented.

Peripheral blood mononuclear cells (PBMCs) are purified by a density gradient centrifugation (Ficoll-Paque) and are available in fresh and frozen (cryopreserved) format.  HumanCells' PBMC are isolated from Leuko Pak (Apheresis-derived) which are highly purified, containing a more pure population of mononuclear cells with higher viability when compared to buffy coat derived cells.

Storage Condition
Cryopreserved PBMCs can be stored in Liquid Nitrogen vapor phase for long-term storage.  Storage in liquid phase nitrogen is NOT recommended. Short-term storage of cells (less than 2 weeks) at -80°C is acceptable but should be minimized to ensure maximum stability. Once thawed, samples must be used immediately, and can not be frozen again.
