Définition western blot
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. Besides detecting the proteins, this technique is also utilized to visualize, distinguish, and quantify the different proteins in a complicated protein combination. WebSep 8, 2024 · Overview Definition. Blotting is an investigative technique used to detect and identify macromolecules, such as nucleic acids Acids Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water …

WebThe greatest advantage of fluorescent western blotting detection over chemiluminescent detection is the ability to simultaneously detect a large number of proteins on one blot, using a process called multiplexing. This relies on choosing fluorophores that fluoresce at different wavelengths and can be distinguished by the digital imager.
