Ultra-sensitive label for lateral flow – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold. NHS-activated gold is provided dried with conjugation kit components that make initial conjugation sweeps easy – no EDC/NHS activation required, just add purified…

NHS-activated 40 nm gold is provided dried with conjugation kit components that make initial conjugation sweeps easy – no EDC/NHS activation required, just add purified antibody and follow our simple protocol. Small reaction kits generally require approximately 2 µg of purified…

Use the BioReady Passive Conjugation Kit to conjugate any proteins to 40 nm and 80 nm bare citrate OD 20 gold particles. Our conjugation kit provides the flexibility to conjugate at any OD from 1 to 20.

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…

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…
