Used in biomedical research to detect and quantify levels of cathepsin B enzyme in rat samples. This ELISA kit is particularly useful in studies related to lysosomal function, inflammation, cancer progression, and neurodegenerative diseases. It enables researchers to assess cathepsin B involvement in tissue remodeling, apoptosis, and intracellular protein degradation. Commonly applied in preclinical studies using rat models to evaluate disease mechanisms and therapeutic responses. Provides a sensitive and specific measurement in serum, plasma, cell lysates, and tissue homogenates.
