1 Million cells / vial. Naïve B Cells express CD19 as well as IgD. A naïve B cell has not yet been exposed to an antigen. Once exposed it will become either a plasma cell or a memory B cell. First Choice Bio’s Healthy Human Donor Peripheral Blood CD19+IgD+ Naïve B Cells (PB-CD19/IgD) are isolated in a single-step process that removes non-B cells as well as CD27+ Memory B Cells, leaving only CD19+ IgD+ Naïve B Cells. All peripheral blood is collected in ACDA by Leukapheresis from fully consented donors that tested negative for HIV, HBV, and HCV.

All protocols are IRB approved.
