Streptavidin tetramer is covalently bound to the particle surface via an amide bond. 40 nm streptavidin gold conjugates can be used for convenient conjugation of any biotinylated antibody, protein or oligonucleotide. Ideal for lateral flow assays and other diagnostics.  Each batch is…

The High Sensitivity Conjugation Kit is a complete “classroom-in-a-box” with detailed protocols to help you produce robust covalently-bound conjugates. This kit is available with our ultra-bright 150 nm gold nanoshells as the reporter particle and includes everything you need to…

40 nm gold colloid for passive conjugation. Citrate is the most common stabilizer used for passive conjugation of antibodies and proteins to gold. The “bare” particle surface is stabilized with weakly-associated citrate molecules that can be easily displaced for adsorption. BioReady…

Gold nanoshells provide an ultra-sensitive label for lateral flow assays – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold. The carboxyl surface can be conjugated to free amines in antibodies and proteins, allowing for greater stability, sensitivity, and…
