Our 20nm gold nanoparticle Goat Anti-Rabbit IgG antibody (GAR) conjugate is manufactured using our InnovaCoat® technology. We have coated our high quality gold nanoparticles with a proprietary surface coat that covalently binds the Goat Anti-Rabbit IgG antibody (GAR) forming ultra stable conjugates. The attachment is irreversible meaning that there is no desorption of the antibody from the gold particle, which is a common problem associated with gold conjugated developed using passive adsorption techniques.

Figure 1. Lateral flow assay of our 40nm InnovaCoat® GOLD conjugated to Goat Anti-Rabbit IgG. The signal intensity of the T-linke clearly changes in proportion to the antigen concentration.
Figure2. Quantification of the T-line signal of the lateral flow assay in figure 1.
Figure 3. 40nm InnovaCoat® GOLD conjugated to Goat Anti-Rabbit run on a sandwich lateral flow assay in the presence/absence of Rabbit IgG. Presence of an antigen can be visually assessed by a signal on the T-Line on the lateral flow assay. The C-line confirms that an assay has run properly and should always be visible.
