While Eastern blotting is conceptually similar to lectin blotting, which detects carbohydrate epitopes on proteins or lipids, the term “lectin blotting” is more commonly used in the scientific literature.It’s important to note that Eastern blotting refers to methods that rely on the specific interaction between the PTM and the probe, distinguishing it from a standard far-western blot. These probes can detect various modifications such as lipids, carbohydrates, phosphorylation, and other protein modifications. Once the proteins are transferred, they are subjected to analysis for post-translational modifications using specific probes.The technique involves transferring proteins or lipids from an SDS-PAGE gel onto a PVDF or nitrocellulose membrane. It can be viewed as an extension of western blotting, which primarily detects protein post-translational modifications (PTMs). Eastern blotting enables the analysis of proteins, lipids, and glycoconjugates, with a particular emphasis on detecting carbohydrate epitopes.Notably, Eastern blot has undergone modifications to develop a related technique called far-western blotting, which focuses on studying lipids separated by chromatography. However, the specific molecule or particle being detected may vary. The principle and procedure of Eastern blotting are similar to other blotting techniques.By detecting the presence of biomolecules in different proteins, researchers can gain insights into the intricate modifications occurring within these molecules. The primary objective of Eastern blot is to identify and study the differences in post-translational modifications across various species.As an extension of the popular western blotting technique, Eastern blot has emerged as a valuable tool in protein analysis. Eastern blot is a powerful molecular biology technique used for detecting post-translational modifications in proteins, as well as the presence of lipids and carbohydrates.Let’s dive in and unlock the potential of this powerful molecular biology tool.
