Western blotting

Western blotting (or immunoblotting) is a widely used method for protein detection, using antibody-based probes to obtain specific information about target proteins from complex samples. It is a routine method in molecular biology, biochemistry, and cell biology fields with a multitude of applications. This method can be used to obtain. Western blotting (also called immunoblotting, because an antibody is used to specifically detect its antigen) was introduced by Towbin, et al. in 1979 and is now a routine technique for protein analysis. Western blotting can produce qualitative and semi-quantitative data about the protein of interest. It is an important technique used in cell.

Western Blotting - an overview ScienceDirect Topic

Western blot (v české literatuře též označovaný jako imunoblot) je analytická technika používaná k detekci specifického proteinu ve směsi s dalšími proteiny, např. ve vzorku homogenátu tkáně či jiného biologického vzorku. Využívá gelovou elektroforézu k separaci proteinů podle jejich velikosti (denaturující SDS-PAGE), popř. podle jejich celkové trojrozměrné. Western blot je metoda používaná pro kvalitativní nebo semikvantitativní detekci určitého proteinu ve vzorku.
