A CAL module that provides solutions of labelled antigen and standard antigen of known concentration, and antigen and antibody of unknown concentration, for the user to carry out the experiments needed to...
Traces the various stages from the uptake of an antigen to the digestion of the antigen by the phagocytes.
The two types of molecules on which the specificity of the immune system depends are the antibodies (immunoglobulins) produced by B lymphocytes and the antigen receptors expressed on the surface of T...
Describes how lymphocytes in the bloodstream of an animal will respond to the appearance of an antigen by producing antibodies to it. Explains the difference between monoclonal and polyclonal antibodies....
Illustrates the principles of radioimmunoassay and demonstrates the techniques involved, using Sephadex as the means of separating bound from free antigens. The antigen that is assayed is insulin and the...
Shows the immune system in standby mode, with lymphocytes constantly patrolling the periphery until triggered by a specific encounter with an invader. Shows the response to the invader mounted by those cells...
Designed to show medical students and MLSO’s how precipitin tests are carried out in the laboratory. Shows the equipment, how it is used and also the interpretation of the results from the analyses. The...
Illustrates the types of cells, their visible structure on staining and their similarities and differences. Protein chains and the antigen/antibody response are discussed and related to the student’s...
Looks at scientific work in the 1970s in the area of human sex determination. Notes that a single protein, the HY antigen, is solely responsible for building male organs, and if it is destroyed, the material...
The ELISA (Enzyme Linked Immuno Sorbent Assay) test is used to measure the concentration of an antibody or an antigen in biological fluid. Shows in detail using graphics and laboratory sequences to explain...
