Lymphoid Cells Lymphoid cells provide long-lasting immunity against microbes and pathogens, and play important roles in fields such as autoimmunity and cancer immunotherapies. ATCC offers authenticated lymphoid cells and optimized media products to immunology and oncology researchers. Our continuous cell lines have been authenticated via multiple methods, including short tandem repeat profiling, cytochrome oxidase barcoding, and microbial contamination testing. The use of human primary lymphoid cells from ATCC further help research obtain clear, confident results by increasing physiological relevance. View Lymphoid Cells Primary Lymphocytes CD4+ T Cells CD8+ T Cells CD19+ B Cells CD56+ Natural Killer (NK) CellsATCC primary lymphocytes have been obtained from multiple donors via institutional review board-approved protocols that follow cGMP and cGTP tissue collection and processing guidelines. PBMCs and Monocytes Peripheral Blood Mononuclear Cells Peripheral Blood CD14+ Monocytes Bone Marrow Mononuclear Cells ATCC offers mononuclear cells from peripheral blood (PBMCs) and bone marrow. Mononuclear cells are a heterogeneous population of cells, consisting of lymphocytes (T cells, B cells, NK cells), monocytes, and dendritic cells. Lymphoid/Leukemic Cell Lines TF-1 JM-1 K-562 U-937 Daudi Jurkat, Clone E6-1 RAW 264.7 Lymphoid and leukemic cells originate in the marrow and then migrate into blood circulation, lymphatic circulation, and lymphatic tissues. Highly authenticated and easy-to-grow, these cells can be used at any point in your cancer immunology studies.
