Lifeline® Human CD19+ B Cells provide an ideal culture model for the study of immunology. These normal human CD19+ B Cells are purified from leukapharesed peripheral blood using immunomagnetic positive selection.
Human CD19+ B Cells are cryopreserved directly after isolation to ensure optimal phenotype and the highest viability and plating efficiency. Our Human CD19+ B cells are quality tested via flow cytometry to ensure the enrichment of CD19+ cells.
Lifeline® CD19+ B Cells are maintained in a suspension culture. B Cells will not proliferate under maintenance conditions.
CD19+ B Cells are not exposed to antimicrobials or phenol red. (Lifeline® offers antimicrobials and phenol red but they aren’t required for eukaryotic cell proliferation.)
