Used in biomedical research to detect and quantify Cathepsin Z levels in rat biological samples such as tissue homogenates, serum, and cell culture supernatants. Enables investigation of Cathepsin Z's role in immune regulation, bone remodeling, and inflammatory diseases. Commonly applied in studies related to arthritis, osteoporosis, and neurodegenerative conditions where protease activity is a key factor. Provides a reliable, sensitive, and specific measurement for monitoring disease progression and evaluating therapeutic interventions in preclinical rat models.
