Cord Blood CD19+ B Cells, Fresh
Human B cells are lymphocytes that are characterized by the expression of CD19 on the cell surface. These cells are one of the main cell types involved in the humoral immune response. Upon activation, due to an encounter with an antigen, B cells will act as antigen-presenting cells (APCs), make antibodies against foreign antigens, and develop into memory B cells or plasma cells.
Human cord blood CD19+ B cells are positively selected using immunomagnetic anti-CD19 microbeads from the mononuclear cell fraction. Isolated cells are characterized by flow cytometry to ensure a highly pure and viable cell population.
Cells were obtained using Institutional Review Board (IRB) approved consent forms and protocols.
