Western blot workflow. The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. [1]
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
Because the proteins may retain or regain part of their structure during blotting they may react with specific antibodies giving rise to the term immunoblotting. Alternatively the proteins may react with ligands like lectins giving rise to the term affinity blotting.
Detection and assay of biomolecules in systems such as ELISA and Western blots; DNA sequencing using pyrosequencing; Lighting objects. Chemiluminescence kites, [17] emergency lighting, glow sticks [18] (party decorations). Combustion analysis: Certain free radical species (such as • CH and • OH) give off radiation at specific wavelengths ...
The intensity of light is a measure of the number of enzyme molecules reacting and thus of the amount of hybrid. ECL is simple to set up and is sensitive, detecting about 0.5 pg nucleic acid in Southern blots and in northern blots. Detection by chemiluminescent substrates has several advantages over chromogenic substrates.
A western blot is used for the detection of specific proteins in complex samples. Proteins are first separated by size using electrophoresis before being transferred to an appropriate blotting matrix (usually polyvinylidene fluoride or nitrocellulose ) and subsequent detection with antibodies.

A ligand binding assay (LBA) is an assay, or an analytic procedure, which relies on the binding of ligand molecules to receptors, antibodies or other macromolecules. [1] A detection method is used to determine the presence and amount of the ligand-receptor complexes formed, and this is usually determined electrochemically or through a fluorescence detection method.
