Used in biomedical research to quantitatively measure levels of Early Growth Response Protein 3 (EGR3) in human biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly valuable in studies related to neurobiology, immune regulation, and psychiatric disorders, as EGR3 is involved in neuronal development, synaptic plasticity, and T-cell activation. Researchers use this tool to investigate EGR3 expression changes in conditions like schizophrenia, bipolar disorder, and autoimmune diseases, supporting both diagnostic research and therapeutic development. The assay enables high-throughput, sensitive detection, making it suitable for clinical laboratories and experimental studies aiming to understand transcriptional regulation in human health and disease.
