What is Western blotting?
Western blotting is an analytical technique used to detect specific proteins in a sample.
Why is reagent quality important?
High-quality reagents enhance sensitivity and reliability of results in Western blotting.
What are the main steps in Western blotting?
The main steps include sample preparation, gel electrophoresis, transfer to a membrane, and probing with antibodies.
How can I improve the sensitivity of my Western blot?
