Used in biomedical research to quantitatively measure Cathepsin B protein levels in biological samples such as cell lysates, tissue homogenates, and body fluids. Widely applied in studies related to cancer, neurodegenerative diseases, and inflammation due to Cathepsin B's role in apoptosis, extracellular matrix degradation, and lysosomal function. Enables researchers to assess disease progression, evaluate therapeutic responses, and investigate molecular mechanisms in both in vitro and in vivo models. Suitable for high-throughput screening and provides reliable, reproducible results with high sensitivity and specificity.
