Western Blot
Western Blot is a fundamental laboratory technique used to identify and analyze specific proteins in biological samples. Think of it like a fingerprinting method for proteins - it helps scientists detect and measure particular proteins they're interested in studying. This technique is widely used in medical research, pharmaceutical development, and diagnostic laboratories. When you see this on a resume, it indicates that the candidate has hands-on experience with this important protein analysis method, which is valuable in many research and clinical settings.

Example Interview Questions
Senior Level Questions
Q: How would you troubleshoot failed Western Blot results?
Expected Answer: A senior technician should explain a systematic approach to identifying issues, such as checking protein loading, transfer efficiency, and antibody quality. They should also mention how they would document and standardize procedures to prevent future failures.
Q: How would you train new staff members on Western Blot techniques?
Expected Answer: Should discuss creating structured training programs, emphasizing safety protocols, quality control measures, and common pitfalls to avoid. Should mention the importance of hands-on supervision and gradual progression from simple to complex samples.
Mid Level Questions
Q: What steps do you take to ensure consistent Western Blot results?
Expected Answer: Should describe proper sample preparation, the importance of using controls, and maintaining consistent conditions throughout the procedure. Should also mention proper documentation of protocols.
Q: How do you determine the right amount of protein to load for a Western Blot?
Expected Answer: Should explain about performing protein concentration measurements, the importance of loading controls, and how to optimize protein amounts based on the target protein's abundance.
Junior Level Questions
Q: What are the main steps in a Western Blot procedure?
Expected Answer: Should be able to list the basic steps: sample preparation, gel electrophoresis, transfer to membrane, blocking, antibody incubation, and detection. Basic understanding of each step's purpose is expected.
Q: What safety precautions do you take when performing Western Blots?
Expected Answer: Should mention proper protective equipment (gloves, lab coat, eye protection), safe handling of chemicals, and proper disposal of materials.
