Western Blot
Western Blot is a fundamental laboratory technique used to identify and measure specific proteins in biological samples. Think of it like a high-tech fingerprinting method for proteins - it helps scientists detect the presence and amount of particular proteins in cells or tissues. This technique is widely used in medical research, drug development, and disease diagnosis. When you see this on a resume, it indicates that the candidate has hands-on laboratory experience and is familiar with protein analysis methods. It's often listed alongside other common lab techniques like PCR or ELISA.
