- Transfer: The separated proteins are then transferred onto a membrane, usually made of nitrocellulose or PVDF.
- Blocking: The membrane is blocked to prevent non-specific binding.
- Antibody Incubation: Specific antibodies are applied to the membrane to bind to the target proteins.
- Detection: The attached antibodies are visualized using various detection techniques, enabling researchers to identify the presence and quantity of specific proteins.
Advantages of Using Western Blot Machines
The use of a western blot machine offers numerous advantages, which include:
- High Specificity: With the use of specific antibodies, researchers can accurately identify target proteins amidst a pool of others.
- Quantitative Analysis: The technique allows for quantification of protein levels, which is crucial in various biological studies.
- Versatility: Western blotting is applicable in numerous fields, from cancer research to microbiology and immunology.
- Validation of Protein Expression: It serves as a robust method for confirming protein expression in experimental samples.
