Home / Products / Off-the-shelf gold conjugates V2 / Primary gold conjugates / Chikungunya Virus (CHIKV E1) Gold Conjugate – 40 nm (Ref NF-CHIKVE1-AU)

Nano Flow’s Chikungunya Virus (CHIKV E1) gold conjugate is built on a highly specific monoclonal antibody targeting the Chikungunya Virus Envelope 1 protein (CHIKV E1). This conjugate has been validated as a detection antibody in lateral flow assays, ensuring robust performance and high specificity for CHIKV diagnostics. The corresponding capture antibody is also available, enabling developers to access a complete antibody pair for rapid and reliable assay development.

This conjugate demonstrates no cross-reactivity with related arboviruses such as Dengue, Zika, Yellow Fever Virus (YFV), West Nile Virus (WNV), Tick-borne Virus (TBV), or Japanese Encephalitis Virus (JEV), ensuring diagnostic accuracy even in challenging endemic contexts. Produced on Nano Flow’s highly spherical 40 nm gold nanoparticles (OD20), it delivers superior reproducibility, stability, and sharp visual signals in test and control lines.

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