BNP Gold Conjugate – 40 nm (Ref NF-BNP-AU)

Home / Products / Off-the-shelf gold conjugates V2 / Primary gold conjugates / BNP Gold Conjugate – 40 nm (Ref NF-BNP-AU)

Nano Flow’s BNP (Brain Natriuretic Peptide) gold conjugate is based on a monoclonal antibody targeting human BNP, a key biomarker for the diagnosis and monitoring of heart failure. Validated as a detection antibody in lateral flow assays, this conjugate ensures high sensitivity and reproducibility in cardiac diagnostics. The corresponding capture antibody is also available, enabling developers to work with a complete pair solution for rapid test development.

This antibody is produced under animal component-free conditions, ensuring consistency and reliability for both research and regulated diagnostic applications. Conjugated to Nano Flow’s highly spherical 40 nm gold nanoparticles (OD20), it delivers superior reproducibility, stability, and strong visual signal intensity across immunoassay platforms.

Applications: Lateral flow assays (LF) and other immunoassay formats.
Certificate of Analysis: Supplied with each batch, including TEM, DLS, and UV-Vis characterization.
