ScienceDirect - devoted to covering techniques for: (1) Quantitating and detecting antibodies and/or antigens and haptens based on antigen-antibody interactions. (2) Fractionating and purifying immunoglobulins, lymphokines and other molecules of the immune system. (3) Isolating antigens and other substances important in immunological processes. (4) Labelling antigens and antibodies with radioactive and other markers. (5) Localizing antigens and/or antibodies in tissues and cells, in vivo or in vitro. (6) Detecting, enumerating and fractionating immunocompetent cells. (7) Assaying for cellular immunity. (8) Detecting cell-surface antigens by cell-cell interactions. (9) Initiating immunity and unresponsiveness. (10) Transplanting tissues. (11) Studying items closely related to immunity such as complement, reticuloendothelial system and others.
