The aim of binding assays is to measure interactions between two molecules, such as a protein binding another protein, a small molecule, or a nucleic acid. Hard work is required to prepare reagents, but flaws in the design of many binding experiments limit the information obtained. See more One of the most common experiments in biochemistry and cellular and molecular biology is testing whether two molecules interact with each other. This includes two proteins binding to … See more Let's begin with a basic, reversible, bimolecular binding reaction: molecule A binds to molecule B forming a complex AB: Conceptually such reactions are straightforward. In the forward reaction (indicated by the … See more Two general options are available to measure affinities. 1) In an equilibrium experiment, one determines the extent of the reaction as a … See more A number called the equilibrium constant characterizes the affinity of molecules for each other. A few simple relationships define equilibrium constants and form the basis for determining … See more WebIt is thought to bind the minor groove of dsDNA and upon binding increases in fluorescence over 100-fold. It is important to note that at very high concentrations it starts to inhibit the PCR reaction. It binds to any type of dsDNA and no probe design is necessary.
