What is the Western Blot Detection System?
The Western Blot technique is a powerful tool that combines gel electrophoresis and immunoassay principles to identify and quantify proteins from biological samples. Developed in the 1970s, this method has evolved significantly, enhancing its sensitivity and specificity over the years.
Basic Principles of Western Blotting
The process of Western Blotting involves several key steps:
- Sample Preparation: Biological samples, such as tissues or cell cultures, are lysed to extract proteins.
- Gel Electrophoresis: Proteins are separated based on their molecular weight using polyacrylamide gel electrophoresis (PAGE).
- Transfer: The separated proteins are transferred from the gel to a membrane, typically made of nitrocellulose or PVDF.
- Blocking: To prevent non-specific binding, the membrane is treated with a blocking solution.
- Antibody Incubation: The membrane is incubated with a primary antibody specific to the target protein, followed by a secondary antibody that is enzyme-linked or fluorescent.
- Detection: The presence of the protein is visualized using various detection methods such as chemiluminescence or fluorescence.
Applications of the Western Blot Detection System
