P38 MAPK Polyclonal Antibody

A lymphocyte is a type of white blood cell in the immune system of most vertebrates. Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an important subtype (which functions in cell-mediated, cytotoxic innate immunity) . They are the main type of cell found in lymph. Lymphocytes make up between 18% and 42% of circulating white blood cells.
