Is a secondary serological test where Ag is soluble not a particulate cell.. A precipitation line appears at optimal proportions of Ag and Ab not equal proportions.. BCH 462 [practical] . Lab#7. Objective:. -To get familiar with radial immunodiffusion.. -To determine the concentration of unknown antigen.. . -Precipitation . reactions are based on the interaction of antibodies and antigens. They are based on two soluble reactants that come together to make one insoluble product, the precipitate (. BCH 462 [practical] . Lab#7.

The immune system is a system of biological structures and processes within an organism that protects against disease.. . To function properly, an immune system must detect a wide variety of agents, from viruses to parasitic worms, and distinguish them from the organism’s own healthy tissue. . Radial immunodiffusion.
