Influenza B (Flu B) Gold Conjugate – 40 nm (Ref NF-FLUB-AU)

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

Nano Flow’s Influenza B (Flu B) gold conjugate is built on a monoclonal antibody targeting the Influenza B nucleoprotein, a highly conserved antigen across Influenza B strains. Validated as a detection antibody in lateral flow assays, this conjugate delivers sensitive and specific performance for Influenza B diagnostics. The corresponding capture antibody is also available, providing assay developers with a complete antibody pair for rapid test development.

This antibody demonstrates no cross-reactivity with Influenza A, adenovirus, RSV, parainfluenza, Mycoplasma pneumoniae, or SARS-CoV-2, ensuring diagnostic accuracy and reliability. Produced on Nano Flow’s highly spherical 40 nm gold nanoparticles (OD20), it offers reproducibility, long-term stability, and strong visual signals across immunoassay formats.

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