Critical Quality Attributes
Critical Quality Attributes (CQAs) are the key characteristics or properties of a biotechnology product that must be within certain limits to ensure the product is safe and effective. Think of them as the essential measurements that show a medicine or biological product meets required standards. For example, just like how food products need to meet certain standards for safety and nutrition, biotech products need to meet specific quality standards. These attributes might include things like how pure the product is, how stable it remains over time, or how strong its effects are. Understanding CQAs is crucial because they directly impact product approval by regulatory agencies like the FDA.
