Verified step by step guidance
1
Understand the context of the problem: The question is about identifying a specific biochemical technique used to detect proteins.
Review the options provided: Southern Blot, Northern Blot, Eastern Blot, and Western Blot. Each of these techniques is used for different types of biomolecules.
Recall the purpose of each technique: Southern Blot is used for DNA detection, Northern Blot is used for RNA detection, and Western Blot is used for protein detection. Eastern Blot is less commonly referenced and is not a standard technique.
Focus on the Western Blot: This technique involves separating proteins by gel electrophoresis, transferring them to a membrane, and then using antibodies to detect specific proteins.
Conclude that the Western Blot is the correct answer because it specifically uses antibodies to detect proteins after they have been separated by gel electrophoresis.
