Ultrasensitive detection of four organic arsenic compounds at the same time using a five-link cardboard-based assay

Preparation of arsenic(iii) monoclonal antibodies and preliminary evaluation of a novel silver-coated gold nanorod SERS immunoassay strip construction

“…The UV absorption spectra of all immunogens or coating antigens exhibited a significant blue shift compared to BSA, KLH, OVA, and ITCBE. Similar observations were also reported in the studies conducted by Xu, 29 where the UV results of immunogens or coating antigens shifted forward compared to the individual proteins or chelators. This shift in UV absorption confirmed the successful coupling of metal ions with the proteins, thereby indicating the successful synthesis of the immunogen and coating antigen.…”

“…28 Since then, significant progress has been made in the field of antibody technology, leading to the development and application of various antibodies targeting heavy metals, resulting in improved performance. In a study conducted by Xu et al , 29 a highly sensitive monoclonal antibody 3F2 was developed through the design of a semi-antigen. This antibody was then employed in the creation of a colloidal gold immunochromatography assay.…”

Multifunctional Eu(iii)-modified HOFs: roxarsone and aristolochic acid carcinogen monitoring and latent fingerprint identification based on artificial intelligence

“…Excessive use of Rox can cause dysfunction of animal tissues and organs, and result in organic diseases, loss of appetite, neurodegenerative disorders, and even cancer. 59 To investigate the sensitivity of Eu@ 1 to Rox, the emission spectra of Eu@ 1 after being immersed in a series of consecutive concentrations of Rox (1 × 10 −3 –2 × 10 −5 M) were collected. As shown in Fig.…”

Monoclonal antibody production and development of immunochromatographic strip assays for screening of the herbicide bispyribac-sodium in rice

“…The immune antigens (BIS-BSA) were injected into the neck and back of mice. 15,16 After the third immunization, blood was collected from the mice and analyzed by indirect competitive ELISA (ic-ELISA). Finally, the mouse with the most sensitive and highest titer antiserum was sacrificed for cell fusion.…”
