Used in research settings to detect and quantify Immunoglobulin G1 (IgG1) in biological samples such as serum, plasma, or cell culture supernatants. This kit is commonly applied in immunology studies to assess immune responses, monitor disease progression in autoimmune disorders, infections, and allergies, and evaluate vaccine efficacy. It enables high-throughput analysis with high specificity and sensitivity, making it suitable for clinical research and drug development. The assay format supports precise measurement of IgG1 levels, aiding in biomarker discovery and therapeutic antibody monitoring.
