Immature lymphocytes
WitrynaLymphocytes are responsible for the astonishing specificity of adaptive immune responses. They occur in large numbers in the blood and lymph (the colorless fluid in the lymphatic vessels that connect the lymph nodes in the body to each other and to the bloodstream) and in lymphoid organs, such as the thymus, lymph nodes, spleen, and … WitrynaLymphocyte Proliferation Assays. Lymphocyte proliferation assays are based on the ability of lymphocytes to proliferate when cultured. Proliferation can be enhanced by mitogens that are polyclonal activators of T lymphocytes (e.g., concanavalin A) or B lymphocytes (e.g., LPS). After 48–72 h of culture, tritiated thymidine is added to …
