ABSTRACT
Qualitative and quantitative analytical techniques are of tremendous importance in all fields and disciplines of life sciences for the detection, identification, and measurement of concentration of a wide variety of biologically important molecules. These analytical techniques can be classified into three general categories: biological techniques or bioassays, those based on physical and/or chemical methods, and those that depend on noncovalent binding of one reactant to another. Techniques that fall under the third category are also commonly referred to as binding assays.
