The reconstituted Veri-Cells? CD34 PBMC can be used for immunofluorescent staining and multi-color flow cytometry assays. The cells can be used as controls for stability studies to avoid donor variability. In addition to CD45 and CD34, these cells have been verified to work with commonly tested cell markers such as CD3, CD4, CD8, CD19, CD20, CD56/16, CD14, CD25, CD69, Granzyme B, Perforin, FOXP3, and Helios.This product contains human cells, a potentially biohazardous material. Blood used in preparation of these samples was tested and found to be negative, using FDA approved methods, for antibody and nucleic acid testing against Human Immunodeficiency virus (HIV), Hepatitis B and C virus and HTLV (Human T-Lymphotrophic virus I and II), surface antigen for Hepatitis B (HBsAg) virus and syphilis and West Nile Virus. Biological tests are not 100% accurate. Use standard precautions when handling and treat as if the product is capable of transmitting disease.
