Nano Flow’s NT-proBNP (AA 13-27) gold conjugate is based on a monoclonal antibody targeting the N-terminal pro-brain natriuretic peptide (NT-proBNP), a key cardiac biomarker used in the diagnosis and monitoring of heart failure. Validated as a detection antibody in lateral flow assays, this conjugate ensures reliable and sensitive performance in cardiac diagnostics. The corresponding capture antibody is also available, offering developers a complete pair solution for assay development.
