Nano Flow’s Protein A/G gold conjugate is a ready-to-use universal detection reagent designed for lateral flow assay development and manufacturing. Protein A/G binds with high affinity to the Fc region of IgG antibodies from multiple species, making this conjugate a versatile tool for a wide range of immunoassay formats.
Protein A/G Gold Conjugate – 40 nm (Ref NF-PROTAG-AU)
Validated for use as a detection reagent in lateral flow assays, this conjugate is particularly well suited for applications where antibody orientation, flexibility, and broad species compatibility are required. Conjugated to Nano Flow’s highly spherical 40 nm gold nanoparticles (OD20), it ensures excellent reproducibility, stability, and strong visual signal intensity.
Applications: Lateral flow assays (LF) and other immunoassay platforms using IgG antibodies from multiple species.
Certificate of Analysis: Supplied with each batch, including TEM, DLS, and UV-Vis characterization.
