Used in research settings to detect and quantify levels of human β2-glycoprotein I (β2GPI) in biological samples such as serum or plasma. This ELISA kit is particularly useful in studies related to autoimmune diseases, especially antiphospholipid syndrome (APS), where β2GPI acts as a major autoantigen. It enables researchers to measure both native and modified forms of β2GPI, aiding in the investigation of immune responses, thrombosis mechanisms, and antibody interactions. The assay supports high-throughput analysis with high sensitivity and specificity, making it valuable for clinical research and biomarker validation.
