Used in biomedical research to detect and quantify rat immunoglobulin G (IgG) in biological samples such as serum, plasma, or tissue extracts. Commonly applied in immunology and pharmacology studies to assess immune responses in rat models. Helps evaluate antibody production following vaccination, infection, or therapeutic treatment. Widely used in preclinical studies to monitor immune system activity and assess the efficacy of drugs or biologics in rat experimental systems. Provides a reliable, sensitive, and high-throughput method for measuring IgG levels in multiple samples simultaneously.
