Used in biomedical research to quantify levels of STAT3 protein in rat samples, this ELISA kit enables researchers to study the activation and regulation of signaling pathways involved in inflammation, immune responses, and cancer progression. It is widely applied in preclinical studies to evaluate the effects of therapeutic agents on the JAK-STAT signaling pathway. The kit supports high-throughput analysis in cell lysates and tissue homogenates, making it valuable for drug development and molecular biology research focused on cellular proliferation, apoptosis, and cytokine signaling.
