Used in biomedical research to detect and quantify cyclooxygenase-2 (COX-2) protein levels in rat tissue samples or cell cultures. This ELISA kit enables researchers to study inflammation pathways, evaluate drug efficacy in inflammatory disease models, and investigate COX-2 expression in conditions such as arthritis, neurodegenerative diseases, and cancer. It provides a sensitive and specific method for measuring COX-2 in serum, plasma, or tissue homogenates, supporting preclinical studies in pharmacology and immunology.
