As the name suggests there is an antigen - antibody reaction between the antigen (Hormone) of interest and its specific antibodies raised from laboratory animals. The quantum of antigen-antibody binding is monitored using a radiolabelled antigen or antibody. In brief the RIA kit contains test tubes which have been coated with the antibody. To these tubes, standards or samples are added (usually 25 to 200 ul volume) along with the tracer, The contents are incubated for 1 - 2 hours and the tubes are emptied by decanting the contents or aspirating. The tubes are washed with the wash solution provided and are counted in a gamma counter. The counts obtained for various known standards used in the assay are utilised for generating a dose - response curve and the unknown concentration in serum samples are extrapolated from the data. \

Principle of Exercise is not one of the three principles of training. The three principles are Overload, Specificity, and Progression.
The Principle of Doubt was created in 1989.
The Pauli exclusion principle states that no two electrons in the same orbital can have the same spin. This principle arises from quantum mechanics and is a fundamental rule that governs the behavior of electrons in an atom.
Archimedes is credited with discovering the principle of buoyancy, known as Archimedes' principle. This principle states that the upward buoyant force on an object immersed in a fluid is equal to the weight of the fluid that the object displaces.

Radioimmunoassay was developed by Dr. Rosalyn S. Yalow and Dr. Solomon A. Berson in the early 1960s. This technique revolutionized the field of endocrinology by allowing the measurement of hormones in small quantities in biological samples.

Rosalyn Sussman Yalow (1921-2011) was an American medical physicist, and a co-winner of the 1977 Nobel Prize in Medicine for her development of the radioimmunoassay process.
