The research tools include recombinant proteins, monoclonal antibodies, polyclonal antibodies, ELISA kits, ORF cDNA clones.
The adaptive immune or specific immune response consists of antibody responses and cell-mediated responses, which are carried out by different lymphocyte cells, B cells and T cells, respectively. B Cells are the major cells involved in the creation of antibodies that circulate in blood plasma and lymph, where they bind specifically to the foreign antigens. Cell-mediated immunity does not involve antibodies but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. When immunologists began to study different kinds of lymphocytes, they began to classify them by the CD antigens that were on their surface, as know as CD4+ T cells are helper T cells, and CD8+ T cells are cytotoxic T cells.
