Blotting
______ (1981) is an Immunoblotting technique which rely on the specificity of binding between a protein of interest and a probe (antibody raised against that particular protein) to allow detection of the protein (cell, tissue, organ, or body fluid) of interest in a mixture of many other similar molecules

Study Notes
Western Blotting Technique
- Western blotting is a hybridization technique used to resolve and detect macromolecules like DNA, RNA, or proteins in a gel matrix, transferred to a solid support.
Immunoblotting
- Developed in 1981, Immunoblotting is a Western blotting technique that relies on the specificity of binding between a protein of interest and a probe (antibody) to detect the protein in a mixture of similar molecules.
Sample Preparation for Western Blotting
- Various sources of protein can be analyzed using Western blotting, including whole tissues, biological fluids, and secreted proteins in vitro.
- Sample preparation involves disrupting cellular membranes and solubilizing target proteins using detergents, salts, and chemical lysis buffers like Tris-HCI.
Western Blotting Protocol
- The Western blotting protocol consists of six steps:
- Sample preparation
- Blotting (or transfer)
- Blocking
- Antibody probing
- Detection
