Product Overview:

Cord blood CD34+ stem cells are isolated using positive immunomagnetic cell separation procedures from umbilical cord blood.

Storage Conditions:

For cryopreserved cord blood CD34+ stem cells, either prepare cells for long-term storage in Liquid Nitrogen vapor phase or thaw for use. 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.

Testing: Donors are tested for HBV, HCV, HIV, HTLV, WNV, Trypanosoma cruzi, and Syphilis.

Cord Blood CD34+ Stem/Progenitor Cells Flow Data

CD45 versus PI flow data
CD45 and Propidium Iodide (PI) are used to assess purity and viability of PBMCs. CD45 is expressed on all leukocytes and is used to indicate purity of the white blood cell (WBC) component. Because PI cannot pass through the membrane of live cells to stain DNA, it serves as an indicator of viability. Representative data shown here indicates purity of 95.09% – meaning >95% of cells in this sample are WBCs. (May not be indicative of received samples.)

CD45 versus CD34 flow data
The CD34 protein is a transmembrane protein expressed on early hematopoietic and vascular-associated tissues. It is the most frequently used cell surface marker for stem cells. Side scatter (SSC) is a measurement of inner cellular complexity. CD34+, when assessed in the CD45+ cell population, is a measure of stem cell purity in the enriched sample. This graph shows a representative data set with stem cell purity of 97.62%. (Representative data only. Actual purity percentages will vary between samples.)
