Used in immunological research to quantify rat tumor necrosis factor gamma (TNF-γ) levels in biological samples such as serum, plasma, or cell culture supernatants. Enables researchers to study inflammatory responses, immune system activation, and disease mechanisms in rat models. Commonly applied in studies related to autoimmunity, infection, and cancer. Provides a sensitive and specific method for detecting TNF-γ, supporting data collection in preclinical experiments and therapeutic development.
