Human Peripheral Blood CD19+ B Cells

Details

CD19+ B cells are adaptive immune lymphocytes responsible for antibody production, antigen presentation, and immunological memory. As the core effectors of humoral immunity, B cells serve as a critical primary cell system for vaccine research, autoimmune disease modeling, oncology studies, and the development of B-cell-targeted therapeutics.

MileCell's CD19+ B cells are isolated from peripheral blood via immunomagnetic positive or negative selection, with every lot validated for high purity, viability, and immunophenotyping by flow cytometry. Available in fresh and cryopreserved formats, they can be used in applications spanning antibody secretion assays, B-cell activation and proliferation studies, ELISpot, flow cytometry, and co-culture with T cells or antigen-presenting cells.
