Flow Cytometry
Flow Cytometry is a laboratory technique used to analyze and sort cells by passing them through a machine that measures their characteristics. Think of it like a high-tech cell sorting system, similar to how a coin sorting machine separates different types of coins. Scientists and lab technicians use this method to count cells, detect specific cell types, and identify abnormal cells, which is particularly important in medical research, disease diagnosis, and drug development. This skill is commonly required in biotech companies, research laboratories, and clinical settings.
