Rocket Immunoelectrophoresis is an adaptation of radial immunodiffusion developed by Laurell. It is also known as electroimmunoassay or electroimmunodiffusion. It is called as “rocket electrophoresis” due to the appearance of … Read more
The innate immune system provides the first line of host defense against microbes, before adaptive immune responses have had sufficient time to develop. The mechanisms of innate immunity exist before … Read more
Immunoelectrophoresis refers to precipitation in agar under an electric field. It is a process of a combination of immuno-diffusion and electrophoresis. An antigen mixture is first separated into its component … Read more
Immuno-diffusion is a technique for the detection or measurement of antibodies and antigens by their precipitation which involves diffusion through a substance such as agar or gel agarose. Simply, it … Read more
Interactions of antibodies and antigens, in the form of various tests, have been developed to determine the presence or absence of antibodies or antigens in a sample. A type of … Read more
