Used in biomedical research to quantitatively measure levels of Early Growth Response Factor 1 (EGR1) protein in human cell lysates, serum, plasma, and tissue extracts. Widely applied in studies related to gene regulation, cellular proliferation, apoptosis, and stress responses. Commonly used in neuroscience research to investigate neuronal activation and synaptic plasticity. Also utilized in cancer research to assess EGR1 expression in tumor development and in immunology to study immune cell activation. The kit enables high-throughput analysis with high sensitivity and specificity, supporting both basic research and biomarker validation studies.
