Used in biomedical research to quantify Human Tumor Necrosis Factor Receptor Superfamily Member 18 (also known as GITR) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is particularly valuable in immunology and oncology studies, where GITR expression levels are monitored to understand immune regulation, T-cell activation, and the development of cancer immunotherapies. It supports research into autoimmune diseases and immune checkpoint modulation by providing a reliable and sensitive method to measure protein concentration, enabling evaluation of therapeutic responses and disease progression in experimental models.
