Gold nanoshells provide an ultra-sensitive label for lateral flow assays – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold. 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 materials are engineered for reliable conjugation to antibodies, proteins, peptides, and other biomolecules. Ideal for lateral flow assays and other diagnostics. Each batch is extensively characterized to meet highest quality standards, ensuring reliable & reproducible results. All products supplied with batch-specific COA's with TEM, DLS, Zeta, & UV-Vis.
