Used in immunological research to quantify levels of the transcription factor T-bet in biological samples, this ELISA kit helps assess T-helper 1 (Th1) cell differentiation and activity. It is particularly valuable in studies related to autoimmune diseases, infectious diseases, and allergic responses, where Th1/Th2 balance plays a critical role. Researchers use it to evaluate immune responses in experimental models, monitor the effects of therapeutic interventions, and investigate cytokine signaling pathways. The assay enables high-throughput, specific, and sensitive detection of T-bet protein, supporting both basic science and preclinical research in immunology.
