This study aimed to prepare monoclonal antibodies against human β2-MG and to establish rapid and accurate quantitative and qualitative immunoassay methods for β2-MG detection. Recombinant β2-MG was produced through prokaryotic expression and purification, and subsequently used for immunizing BALB/c mice. Monoclonal antibodies against human β2-MG were generated using hybridoma technology and screened via double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), which facilitated the development of a chemiluminescence enzyme immunoassay (CLEIA). Clinical serum β2-MG levels were measured to evaluate and analyze the detection performance of the proposed CLEIA. Additionally, a convenient and rapid colloidal gold immunochromatographic assay for β2-MG detection was preliminarily established. The monoclonal antibody pair 5H7/6H9-AP was developed into the CLEIA, demonstrating a linear range of 0.14-120.00 μg/L (extended to 60.00 mg/L). The serum β2-MG CLEIA results showed excellent correlation with the latex enhanced immunoturbidimetry assay conducted in hospitals (R2: 0.96, P<0.000 1). The established colloidal gold immunochromatographic assay exhibited good sensitivity for detecting recombinant β2-MG, with test strips capable of detecting a minimum concentration of 0.20 mg/L. The prepared monoclonal antibodies for β2-MG, along with the established quantitative and qualitative immunoassay methods, hold significant potential for clinical diagnostic applications.
